It was definitely an interesting time. That said, the summer of '78 I was renting a room from an IBM engineer who had bought a Heathkit H-11 and was using it to trade stocks. They would enter the prices from the Wall Street Journal every day of the stocks they were interested it, and then run their "algorithm" over them and it would spit out "weights" for buying or selling various stocks. They could then call their broker and have them execute a trade.

As part of my 'rent' I could help out by entering numbers or verifying numbers for him. I discovered that his portfolio was worth more than $4M and I asked him why he was working at IBM if he was "rich". His answer was that he enjoyed working at IBM, you could just "spend" stock as you would lose out on future growth, and what would he do with his time if he wasn't working? The one conceit he admitted was that his house was paid for so he didn't have to pay a mortgage and that meant he had more disposable income every month.

That was a pretty amazing for me at that age.

The other random factoid was that for 10 years I was President of the "Home Brew Robotics Club" (which is still going on) and it was a direct outgrowth of the Home Brew Computer Club. It was started by Dick Prather as a "SIG" or Special Interest Group where HBCC members who were interested in using their computers with robots would meet and exchange ideas and such.

what would he do with his time if he wasn't working?

In a world so full of interesting, wonderful and curious things, I will never understand people who can't think of anything to do if they didn't have a job. Money is usually a limiting factor, but it sounds like it might not have been for this person.

ChuckMcM · 2d ago
I will never understand people who can't think of anything to do if they didn't have a job.

Let me ask you a question and perhaps it will help?

What if there was something wonderful and curious that you could explore and someone else would actually pay you money while you were exploring that thing?

I've met a number of folks in research who "work" at a University doing their research and even though the pay sucks love what they are doing. You could pay them nothing and they would still love doing it. They might be forced to do something else if they didn't have enough money to live on, but even if they had millions and millions they wouldn't be doing anything differently.

Keith, the guy I was renting the room from, was in the latter position. He didn't "have" to work, and didn't "have" to work at IBM to work on computers, but in doing so he got to satisfy his curiosity and got to work on much better equipment than if he were funding it himself. Is that something understandable?

FWIW, in the Bay Area we call this "failing" at retirement :-) Failing is in quotes because if you choose to go back to work is it really a failure? Had a great conversation with Guido von Rossum when he decided to 'un-retire' and go "work" for Microsoft. There are a lot of things to like about the office, a community, a continual stream of interesting problems to solve, Etc. And knowing that if you didn't like it you can just stop really helps in dealing with people who would attempt to assert power over you.

> What if there was something wonderful and curious that you could explore and someone else would actually pay you money while you were exploring that thing?

The days of patronage are basically over; no one pays you real money to explore anymore. Corporations only pay you money to exert your brain towards some goal. There may be an exploration phase but well over half the work will be the grind of bugfixing and maintenance (or equivalent in other fields) that is the actual reason for your employment.

ChuckMcM · 1d ago
Could you say more about that? I don't think of it as patronage and I agree with this statement: "Corporations only pay you money to exert your brain towards some goal." but in my experience you can go to a corporation and say "I'm really interested in working on <this thing>, are you interested in that sort of stuff?" And if they are they'll start paying you money to explore that thing with them. I did exactly this the first time I "retired", I'm really fascinated by software defined radio and I was exploring how it works and what one could do with it and a friend said, "I'm working at a company that needs help understanding how to do repeatable software and they are doing a lot of SDR work." Which led to a conversation with the CEO that led to a job offer where I helped their software teams get better and I got to use the multi-million dollar RF lab to continue my explorations. Granted my role was "technical leader" and not "programmer" but how I spent my time was a joint agreement between the company leadership and my interests. I wouldn't expect a company doing accounting software to pay me to design SDRs of course.

And if you passion is something completely different then that can be the case too. A executive I met at IBM retired and has gone head first into their actual passion which is art history. They didn't major in it at school or try to get a job in it because those jobs didn't pay them what they wanted but now that they are retired they are spending their time in libraries and museums all over the place digging into the nuances of various bits of art. Are they "working"? Yes in the sense that they are doing the same thing they would have done if someone had hired an art history major apparently :-).

keiferski · 1d ago
Getting paid to work on your hobby only works if your hobby is somehow tangential to industry. For technical people, this isn’t really a big issue, because we live in a society that puts technical achievements (which result in profits) above pretty much everything else.

But for non-technical people, getting paid by a corporation to work on your hobby is mostly impossible, no matter how important the problem is. No company is going to fund things which are deemed important yet don’t make anyone money directly.

DrillShopper · 1d ago
"Hey, HP? I'm really interested in working on a new way to tie flies for fly fishing, are you interested in that sort of stuff?"

I wonder why I haven't heard back....

smokel · 1d ago
There are still people with too much money who want to do good. In the art world, for example, it is pretty common to sponsor promising artists in one way or the other.

Unfortunately, it turns out that the problem of picking the right person to donate to is a very hard one.

And the amounts of money involved might be on the low end of your expectations.

ghaff · 1d ago
I think the problem with doing this at companies is that there tends to be a lot of BS associated with actually working at a company (good things as well but not sure as much in a largely remote situation).

I try to do some interesting stuff including going to some selected events (who will mostly comp my attendance) in locations I can do some other activities in conjunction.

paulcole · 1d ago
> What if there was something wonderful and curious that you could explore and someone else would actually pay you money while you were exploring that thing?

The latter part of this is irrelevant if you’re rich.

I have no issue with someone who is rich who chooses to do what most other people consider work.

The issue I have is someone who says, “What would I do if I wasn’t working?” Figure it out. You’ve got infinite options. Consider enough of them to be confident in your choice.

If you’re just defaulting to “working” because you haven’t really tried anything else, that’s what I don’t get.

ChuckMcM · 1d ago
I don't know anyone who "defaulted" to working when they didn't have to. I do know several people who actively avoid explaining why they are working to people who don't have the choice to work or not.
paulcole · 1d ago
Huh? Isn't that what the IBM guy in your original story was doing?
ChuckMcM · 1d ago
Misunderstanding, I asked him that exact question which was "Why are you working when you could be doing anything you want?" and his response was that he was doing what he wanted. It was a conscious choice. I've mentioned this before but I joined Sun Microsystems the Monday after they had gone public on Friday. As a result I had a unique opportunity to become acquainted with a large number of people > 1000 who had become suddenly wealthy. The observation was that some of them wanted "big things" and some of them wanted "small things." It seems to be an individual preference thing. But mostly people didn't become 'asshole rich people'[1], the majority went off to do the thing they enjoyed doing. One of my co-workers left Sun, paid off their house, and spent their time doing hobby robotics stuff. If you're a curious person with average or better intelligence, working is much more preferable to being bored. That was Guido's complaint, he could do what ever he wanted but he was bored, and one thing "work" does is supply a bunch of things to do.

[1] Some did of course and the contrast was super stark, why live your life antagonizing those less fortunate than you? It's a choice but I never felt it was a healthy one.

rendx · 1d ago
> and one thing "work" does is supply a bunch of things to do.

and a social environment. "belonging" is a very important human need.

paulcole · 1d ago
> If you're a curious person with average or better intelligence, working is much more preferable to being bored.

If you're a curious person with average or better intelligence you'll never be bored.

ChuckMcM · 1d ago
My mom told me that once I learned to read I would never be bored. Turns out that wasn't accurate :-)
HeyLaughingBoy · 1d ago
I'm pretty sure that guy didn't go around telling people "I'm rich but I only do this job because I like it."
paulcole · 1d ago
I don't understand this comment. He literally did tell a person this.

> I discovered that his portfolio was worth more than $4M and I asked him why he was working at IBM if he was "rich". His answer was that he enjoyed working at IBM, you could just "spend" stock as you would lose out on future growth, and what would he do with his time if he wasn't working?

HeyLaughingBoy · 8h ago
There's a difference between answering a specific, pointed question versus openly advertising the fact.
paulcole · 3h ago
Yes, but I don't see how this is a useful insight at all.

People keep all sorts of things to themselves unless asked and even when asked.

glimshe · 2d ago
I agree with you in principle. At the same time, analysis paralysis and lack of focus can be problems. When you can do 1000 things, what will you pick? Also, are you going to persevere through bumps if you could switch to other 999 things?
freeone3000 · 2d ago
Than working at IBM in peak-mainframe era? I could not imagine a more exciting place to be at that time!
kragen · 1d ago
You could not imagine a more exciting place to be in 01978? How about Xerox PARC, Microsoft, Apple, the MIT AI Lab, Symbolics, LMI, SRI-NIC, Tymshare, Intel, Mostek, Zilog, Control Data Corporation, Cray, Commodore, HP, Texas Instruments, Tandem, DEC, Data General, Linear Technology, Signetics, or CompuServe? You could spend your time inventing things that changed the world for the better, instead of in pointless political maneuvering within IBM to ship products everybody hated.

What are the nearest equivalents today?

emmelaich · 1d ago
For many people, mucking around with computers is a hobby that happens to pay pretty well.
Gollapalli · 1d ago
He was a guy interested in computers working at IBM at a time when computers were just getting going.

It'd be a bit like working at Google and being really interested in the internet at a time when it wasn't essentially an alternative to consulting for upper-middle class college grads.

Someone · 1d ago
> Money is usually a limiting factor, but it sounds like it might not have been for this person.

Might not have, but still could have been. Chances are that, in 1978 at IBM, he had the opportunity to work with hardware that he couldn’t afford to buy.

Similarly, today, a millionaire might choose to stay in a job at SpaceX because it’s the only way they can afford to work with truly big rockets.

protocolture · 1d ago
Lmao, if I had 4 million bucks I would probably be maintaining some old 70s era mainframe trying to get it to do dumb shit like messing with stocks.

This guy got to do it AND got paid.

WorkerBee28474 · 2d ago
According to [0], 4 million in August 1978 is 19.5 million today.

Sounds about right. I certainly thought it was "infinite" money at the time.
mrandish · 2d ago
While the "hobby computer club culture" is known for introducing Steve Jobs to Woz, I suspect it enabled many thousands of similar life and industry changing personal collisions. It certainly did for me. In 1982 my teenage self started a local computer club for my 4K 8-bit Radio Shack Color Computer which I promoted by printing up flyers and driving around to a dozen Radio Shack stores and convincing the managers to post them near the computer. The first meeting was at my house with a dozen or so people but quickly outgrew that and moved to a local community center. I mostly started it because there was a lack of information that was specific to the computer I owned except for two hobby-level monthly 'zines (only available by subscription) and I didn't have any computer knowledge myself (or know anyone with a computer).

Fortunately, a fair number of people who came to the club knew more than I did about our computer and computers in general. I acquired much of my early computer knowledge from those people as well as getting my first two programming jobs through club contacts despite having no resume or computer-specific education. Eventually the club grew to several hundred people, became a registered non-profit corporation and had a volunteer board of directors (who were all older and more experienced than I was about, well - almost everything). I describe myself as a "self-taught programmer" but a good part of that was also being informally 'club-taught' because I had people to ask when I got stuck. They may not have always had the answer but hearing how they thought through solving it was also an education.

I can trace back my entire life-long career as an (eventually) successful serial entrepreneur in desktop computer-centric software and hardware to that club I naively started 45 years ago - and I still have five close friends I met at the club despite all of us moving across the country and around the world several times. And each of those friends has gone on to have notably interesting and productive computer-related careers too.

bityard · 2d ago
This happened a couple decades later, but my first FOUR tech jobs came from attending a local Linux user group and networking with the people there.

I was talking to someone and explaining that I was taking classes at a local community college in preparation for computer science degree and mentioned off-hand that I might try to find some part-time Linux/BSD sysadmin work at some point. (I never fully attained the degree but also ended up not needing it.) The owner of a local IT consulting business overheard me and called me up the next day. I worked for him for a while and the next three jobs I moved to after that were all based on referrals and recommendations from people in that group.

jjav · 1d ago
I am also a Radio Shack Color Computer alumni, owe my career to it. I started using OS-9 as soon as I could afford to upgrade to 64K RAM, to which I thank feeling right at home with SunOS after I got access to that in the university.

To anyone unfamiliar, which is probably most people, OS-9 was a multi-user multi-tasking operating system which ran on 6809 CPUs. While not a UNIX, it was similar enough that the transition to SunOS was smooth.

To this day, I still alias "ls -la" to "dire", which comes from my muscle memory of typing "dir -e" in OS-9!

I have been thinking about this recently. The people building those hobby computers at the time were spending huge amounts of money on building devices that were arguably not useful at all for anything practical. It was pure exploration of new ideas.

I have a feeling that we live in times of over-commercialization. Today, if you build something, the first criticism you'll hear is, "I can get something cheaper that is mass-produced in China." The second thing you'll hear is, "How do you monetize this?".

I think this puts a huge damper on innovation, especially among hobbyists.

PaulRobinson · 1d ago
You touch on two interesting, intertwined topics that don't seem connected at first, but they just connected for me.

I'm not sure it's all necessarily about over-commercialization, but it might be over-globalization.

We're obviously going through a timeline of the US trying to roll back globalized supply chains, and we don't know how that will end, but the one benefit it gave Americans cheap stuff at a cost of that production happening in the US. The benefit of cheap stuff will slowly be eradicated in the name of providing more job security in the US (at least, that's the plan - many are not convinced it makes much economic sense).

Everyone has benefited in some way from globalization (cheaper stuff means more economic utility), but we've also faced economic peril: off-shoring work means there is less work available near by. This is obviously true of blue collar work, but I think most people in the tech industry are familiar with Indian, Eastern European and Philippine companies taking work too.

In most of the West, there seems to have been an assumption that the West would become dominated by "knowledge workers" - all work would move to white collar professional office-bound, screen-based work - while the dirty and hard work of turning base materials into useful products, the blue collar stuff, would move off-shore. Within white collar work, the West would become more "managerial", more strategic, less productive in a tactical sense.

This idea isn't entirely new. Slavery and multiple empires were predicated on similar ideas, and while off-shoring isn't exactly modern slavery, the idea of paying poor people very little money so we can benefit does feel philosophically aligned, shall we say.

It's left us in a place where most people - both in the West and in those countries with off-shored work, and at very work layer from the hardest manual labour all the way up to managerial, perhaps even executive, levels - are worried about their economic future.

How can you have time for hobbies when you're worried about surviving the next 5 years?

This means people are now, more than ever, looking for things that raise their own utility - can I earn more money, and can I buy things cheaper? If you're doing something that doesn't move the needle on one or both of those sides of the equation, you start to feel like you're being left behind and the World is going to eat your lunch, and maybe you and your family too.

In that context, there's not much space for hobbies. Hobbies were a luxury only the affluent could afford hundreds of years ago and as wealth inequality rises again after decades of historic lows, the anxiety is starting to chip away through the middle classes and into the working classes again, so that hobbies won't exist again for many people over the next 20 or 30 years.

And yes, it does harm innovation. Most scientific and technological advancements of the last 500 years were started by people having the time to muck about with things, either as a hobby or as a paid vocation in a research lab or academic setting. That's potentially going away bit by bit. Curiosity has limited value in the future, as it becomes an extravagance few have time or resource for. Many people are subconsciously or even consciously asking themselves: if something doesn't lower a price on things I'm buying or increase the money I can get for what I'm selling, and it can't do that now, why do I care?

It's incredibly sad.

MSFT_Edging · 1d ago
I've been thinking about this too. I'll sometimes run across some part of the Chinese internet where people are creating some niche product to sell on aliexpress. It's less about IP and more about the product. They're inherently short lived and typically evolve past the original idea.

One huge advantage they have is its comparatively dirt cheap to make mistakes and turn another revision. With the tariffs, this more than doubles for the American trying to also make things. When mistakes cost 2-3x, less people are going to take risks. We've been so focused on what we can turn into intellectual property that we lose focus on what we can make.

The benefit of less enforced IP is that designs can be taken and iterated on freely while in the world of strong IP, you get what the company has decided is the product.

So we can observe a low-risk, lowish reward system that rewards continuous improvement over stagnation. I have a bad feeling that we're doubling and tripling down on this to move towards a world where we can only access computing through the narrow lens that the IP holders will allow.

jwr · 1d ago
I've been thinking along similar lines when I tried to figure out if the obsession with getting something cheaper is a cultural thing, or an actual necessity. I think it's a mixture of both, and I agree that economic anxiety does play a part.

You might like Evan Doorbell's YT channel then – he has a lot of old tapes from his misspent youth traveling the world on Ma Bell's dime, and has posted a lot of videos explaining it all for a generation (like mine) without any frame of reference.

Evan's stuff is excellent and worth watching/listening to.

Shameless plug: if you like his stuff, you might also like my book, "Exploding The Phone", which is a history of phone phreaking. https://explodingthephone.com/

Evan narrated the Audible version. :-)

The first buyers of Altair could not find it in any shop. Every transaction occurred via a check sent to MITS, sight unseen, in the hopes of receiving a computer in exchange.

I remember looking at lots of the add in the back of all the magazines and comic books (and paperbacks) being amazed at all the stuff on offer. Just send a check or money order and get you own ...

Then in the 1990's with internet commerce getting started I remember a lot of skepticism with comments like "who would send money to someone they have never met".

No drawing any conclusions here, just looking back and seeing similarities and changes.

kens · 2d ago
I remember the big 1977-1979 scam with DataSync, World Power Systems, and "Colonel David Winthrop" advertising S-100 boards and other computer stuff but not shipping it to purchasers while also ripping off his suppliers. The article mentions Colonel Whitney (not Winthrop) for some reason

Interesting article on it: https://medium.com/@madmedic11671/forgotten-fraud-world-powe...

cfmcdonald · 2d ago
Author here. Thank you for the reference, this is very helpful. The name "Colonel Whitney" came from a 1984 Stan Veit article: https://www.atariarchives.org/deli/computer_magazine_madness...

Obviously he misremembered the name. I wasn't able to find other references to corroborate more details of the scam, but of course now I know that I wasn't searching for the correct name.

ToucanLoucan · 2d ago
That quote bugs me a little because it presumes that mail order hadn't existed before then, that it was some sort of "act of faith." Sears was selling whole ass houses via the mail in the early 1900's, that's where the term "Craftsman home" came from; it's literally the then-owned-by-Sears brand.
Teever · 2d ago
Yeah but Sears is a reputable company selling reputable brands that became so ubiquitous as to enter into the lexicon.

That's miles apart from some fly by night catalogue with ads from Jim Bob selling what was only a decades prior the domain of science fiction and corporate offices.

Like look at it another way. If some fly by night website was selling what they claimed was a desktop replicator for $5000 and someone posted it on Hackernews the top comment would be about how the website isn't responsive and the language is in broken english and somewhere towards the bottom would be a flame war started by some curious person saying "I'm gonna go for it. I just bought it."

quesera · 2d ago
> that's where the term "Craftsman home" came from

FWIW, this etymology is incorrect. The American Craftsman architecture style was a derivative of the British Arts & Crafts movement, post Victorian era.

Timeline is roughly: Arts & Crafts circa 1880, American Craftsman circa 1900.

The Sears Craftsman brand was created in 1927.

bityard · 2d ago
Yes, but there was still fraud. You didn't send your money away to just any random ad you ran across. Sears was VERY well known. And if you didn't know the company or its reputation, you likely wouldn't send your money away to buy something without at _least_ hearing a positive experience from someone you know and trust.

MITS was not unknown, but they were not a household name. And any microcomputer at that time was quite an expensive toy. Costing an amount that a lot of people could not really afford to just lose.

WillAdams · 2d ago
The difference here is that orders placed by USPS mail were subject to mail fraud regulations _and enforcement_ --- that was _not_ in place for early internet ordering.

My kids were quite amazed when they found my copy of a book whose approximate title was _Specialty Mail Order Catalogs_, which is apparently so obscure I'm not finding it on Goodreads or Abebooks --- will have to check the ISBN the next time it comes up and add it to the former.

AStonesThrow · 2d ago
My father's stereo system was installed in our living room, a Heathkit with discrete components, probably a tube-transistor hybrid type. I did not witness him in the process of assembling it.

But in those days, there were the trade magazines on the newsstand, the electronics shops and clubs where guys hung out to talk about calculators and radios and jukeboxes and pinball machines.

It looks like MITS was already into calculators and model rocketry. And getting featured on the cover of Popular Electronics gave them a boost. Undoubtedly, plenty of ads in the back for mail-order kits, and then you'd be signed up for ever-more specialized company catalogs.

It was the same when I collected vinyl records and built computers. Find the right trade magazines and the crusty old guys tending storefronts, and you could learn about the next big thing.

Of course there were also comic books sold to gullible children with catalogs and ads in the back pages. Snapping gum, whoopee cushions, spy cameras, and X-ray Specs. You could count on being disappointed by purchasing something on that list, but it was often a matter of clever misrepresentation by marketing blurbs and a sketch.

One night 8-year-old me phoned in an order for a "remote control hovercraft". It came "collect-on-delivery" which Mom didn't like. The hovercraft was not radio-controlled as I had imagined. It had a flashlight-like handle that held 2x "D" cells and a motor that rotated a thin cable. The cable stretched several feet to a "hovercraft" with a light plastic hull and fan blades. So you could walk it around the room like a marionette as the downdraft held it suspended a little bit.

Only a few years later, I began receiving mail from AARP. The hovercraft sellers had sold them my address and pseudonym. We could tell, because the hovercraft-selling lady had misspelled my first name. Good times.

I had one of those, though I knew what I was getting (from Edmund Scientific Catalog).

I loved that catalog as a kid. American Science and Surplus is probably its spiritual descendent if not quite the same thing.
HeyLaughingBoy · 1d ago
Edmund at least held on to the non-professional side of its optics business through Anchor Optical Supply. But yeah, I miss paging through the original catalogs. I think I still have the "How to make a Telescope" book although I lost the mirror blank several moves ago.

Once upon a time I actually bought (and sold!) stuff on ebay (or rather, auctionweb, at ebay.com/aw, the auctions were only a part of the site!) with postal money orders. After all, a fraudster would be caught out by bad feedback! The internet felt a lot cozier then.

I’ve always been really loved the bicycles for the mind metaphor and for a while I was cataloging different ways the metaphor works for me. Not sure what I did with that list, but compiling it was fun and made me think about how I chose to use technology.

It feels like the era of the personal computer ended around the turn of the century though.

WillAdams · 2d ago
As a person who has finally arrived at a programming setup which allows him to finally do what he has dreamed about since first trying to sketch things up on a Koala Pad attached to a Commodore 64, I would like to gainsay that the personal computer revolution has come to an end.

When OpenSCAD was first released, I finally had a 3D modeling environment which made sense to me.

When the Shapeoko was first announced on Kickstarter (which made use of the opensource projects Arduino, Grbl, and Makerslide, and was iself initially opensource) I finally had a robotic shop assistant which allowed me to make pretty much anything I wanted w/o the need to make myriad fixtures and jigs or to limit myself to traditional joinery techniques.

When Python was added to OpenSCAD as: https://pythonscad.org/ I finally had a programming environment which allowed not just 3D modeling but also mutable variables _and_ the ability to write out files so as to make DXFs or G-code.

So, I am working on:

https://github.com/WillAdams/gcodepreview

and have been using it for my personal projects for a while now --- hopefully I will have a suitably intricate project ready to function as a showcase for its capabilities in a month or so.

criddell · 2d ago
That looks really cool and I like that it isn’t a website. There’s a Whitfield Diffie quote I’ve mentioned a few times on HN. It’s from Ellen Ullman’s book Life in Code[1]:

> We were slaves to the mainframe! [Diffie] said. Dumb terminals! That's all we had. We were powerless under the big machine's unyielding central control. Then we escaped to the personal computer, autonomous, powerful. Then networks. The PC was soon rendered to be nothing but a "thin client," just a browser with very little software residing on our personal machines, the code being on network servers, which are under the control of administrators. Now to the web, nothing but a thin, thin browser for us. All the intelligence out there, on the net, our machines having become dumb terminals again.

Applications like yours claw back a little of that power. Very nice.

Yeah, I've never understood how folks who managed to escape from the schackles of mainframe central computing are willing to ease into the padded cell afforded by cloud computing.

Just to pick a turning point of sorts, it ended when you needed to password protect your "account". In short, the internet killed the "personal" computer.

I think LLMs will bring it back. This is one part of the future I'm hopeful about.

On the other hand I was thinking something similar with smartphones and look how that ended up.

Before those came along I was perfectly content using a computer with 4 or 8 GB of RAM or less and thought that ought to be more enough for anything I wanted to do with computers for the rest of my life. Now I find myself wondering how much more RAM and what new GPU I am going to need to run a model with tens or hundreds of billions of parameters. A few years ago I might have agreed with those who say the personal computer revolution has long been over. Indeed there was a long period with few new milestones or innovation. But now I see that that sentiment was mostly a failure of my (and their) imagination.

> …personal computers have already proliferated beyond most government regulation. People already have them, just like (pardon the analogy) people already have hand guns. If you have a computer, use it. It is your equalizer. It is a way to organize and fight back against the impersonal institutions and the catch-22 regulations of modern society.[28]

And now look where we are at, we allowed impersonal institutions to use them against us.

Remember, there was no Internet, so all info you got was by word of mouth from fellow enthusiasts, or from a few magazines, which were only to be found in a special newspaper shop in a nearby major city to which you made a pilgrimage by train every month.

The 'hobby' computers were no to be found in any 'regular' shop, but sold in what would now probably be called 'pop-ups' run by an enthusiast from his front room.

There was no software to be found, so you programmed everything yourself not for utility but simply for the joy of programming.

There were no standard architectures in the space, not even in terms of display or input. You had things like the Newton with a single line led display, the ZX81 with a membrame 'keyboard' or the Vic-20 with real video out (mostly PAL for europe).

You'ld travel with a little kaggle of friends to a regional 'hobby computer expo', which meant the region's pop-up store owners each had one or two computers set up on a table in some school's gym, and stare in awe at the 'advanced graphics' of the precursor of the BBC Micro that could display the (static) television test card in 8 bit.

The address given for the Byte Shop, "1063 El Camino Real in Mountain View", is ambiguous. It needs to specify either 1063 EAST El Camino Real or 1063 WEST El Camino Real, two quite different locations.

Neither of those matches the store that I remember patronizing circa 1978 or so, to buy a California Computer Systems S-100 box. That would have been on El Camino just north of Grant Road, circa 80 W El Camino.

It’s West. If you look at google maps for that location, there is a landmark pinned for “The Original Byte Shop”. There you can see a B&W photo from back in the day.

I wonder whether the hobbyist/hacker mindset versus the big metal mindset has anything to do with Cutler's distaste for Unix.
hollerith · 1d ago
Early Unix is not the product of hobbyist culture, but rather of an elite institution (Bell Labs) that only hired from the top science and engineering schools. The other institution involved in the early development of Unix was the CS Department of UC Berkeley, whose work was funded by DARPA, which is approximately the complete opposite of hobbyist culture.

When DARPA started funding the addition (by Berkeley CS Dept) of a TCP/IP stack to Unix in 1980, hobbyist culture was about 2 years into the start of its experimentation with the BBS. Specifically, according to Google Gemini, "The very first [BBS] for personal computers, named CBBS (Computerized Bulletin Board System), officially went online on February 16, 1978".

It is interesting to notice how the Unix design filtered down to hobbyists. Bell Labs started sharing Unix (at first, only with other elite institutions) and one reason the decision makers at the corporation (AT&T) that owned Bell Labs was willing to sign off on the sharing was that they had little hope of ever making any significant money from Unix because AT&T had entered into an agreement with the government that it would not enter the computer market. (At the same time, IBM agreed that it would not enter the telecommunications market. The thinking of the government was that each megacorporation was a monopolist or near-monopolist in its market, which would give it an unfair advantage in entering related markets.) Because of this sharing, it was on Richard Stallman's radar in 1983 when he chose to model his GNU system on Unix. Note that at the time Stallman was also an employee of an elite institution (MIT's AI Lab).

Richard Stallman free-software movement was the main force driving the Unix design into the hands of the hobbyists, but it took almost a decade for it to do that. When David Cutler arrived at Microsoft in October 1988 to start the NT project, Unix was still mainly associated with elite institutions.

ghaff · 1d ago
I think it's different. Cutler's alleged distaste for Unix (don't have first-hand knowledge) was that he viewed it as basically a product of ivory tower academics as I understand it.
ferguess_k · 1d ago
Thanks, I got the impression from this podcast, but I could be wrong as I listened it while driving :D

There are various versions of the relationship between Cutler and Unix. Showstopper has one. Bryan et al may have another. And there are doubtless multiple others.

I'd argue that this hobby computer culture is still alive in well, but in a different form: the large number of vintage computing hobbyist groups that work to restore, understand, and make new hardware for the simplistic systems that formed the early days of computing. They enjoy the same optimism that drove the early hobby culture, but from a different vantage point - one of research and understanding - but the enjoyment and excitement are still there.
kragen · 1d ago
There's enjoyment and excitement, but rather than the optimism of an unbounded future of unimaginable wonders, in my experience they're animated by a profound pessimism about the current state of computing and where it's going.
austin-cheney · 1d ago
The article is talking about hardware, but it largely applies to software just the same.

As a former JavaScript developer and a hiring manager who conducts interviews I would never hire a JavaScript developer who has not completed and published a personal application. To be very clear I don't care what your past titles are. You are not a senior developer if you have not written an application. You are not a leader, or team lead, if you have not managed people.

I used to get a free subscription to BYTE in the early 80s, probably through Scholastic. Had no understanding of the code or the images I was looking at but never stopped looking or trying to get it. Byte in particular was pretty thick for a magazine. I believe it had a spine like a book if I'm not mistaken ...
PaulRobinson · 1d ago
Computer Shopper was basically 900 pages of adverts with some editorial and reviews here and there to make people want to subscribe.

BYTE was a little less obnoxious about it, and the quality of the writing was superb. I got it occasionally as a teenager in the UK and always looked forward to it, because the information density was insane. I have the "Best of BYTE" book, and often dip into it as a comforting, sentimental read. I really do wish a magazine like it existed today.

WillAdams · 1d ago
Many of the early computer magazines were quite thick --- the TRS-80 magazine was quite dense, and I spent a lot of time entering computer programs from them.

Byte gradually lost page count over the years... May 1991 was 388 pages, while Oct. 1995 was 250.

greenbit · 2d ago
I recall those being easily half an inch thick on a regular basis, with a definite squared-up binding.
phendrenad2 · 1d ago
People still build their own computers. Just the other day I saw a (relatively recent) design for an Intel 486 motherboard. The only difference is they don't really do anything with these hobby computers.
kragen · 1d ago
The article says, "Discussion of practical software applications appeared infrequently. One intrepid soul went so far as to hypothesize a microcomputer-based accounting program, but he doesn’t seem to have actually written it." So I think building hobby computers you don't really do anything with was already a popular activity at the time.

Alongside the "excessive discussion of “super space electronic hangman life-war pong” were hardware hackers hooking up an S100 bus to AppleIIs or running CP/M on some weird machine via a z80 add-on card.

The other classic, risible, software discussion were hackers suggesting writing a recipe database program. Typically to keep their (typically female) partner from condemning their hobby as a waste of time.

Back in 1977 I worked as a young lawyer in a firm of 10 which used a mimeograph machine in the basement to print (smelly) blue printed sheets of paper used for timesheets to record billing information. Case information was stored on index cards in different metal containers: one kept by file number; another kept alphabetically with multiple cards for every party to a case.

In 1978 I bought a Tandy Model I. In 1979 I joined a friend and we started our own firm. Before the end of 1980 our firm was using my Model I to track attorney time and send detailed billing statements to business clients. By 1984 Compaq computers had replaced every electric typewriter in my firm and were running billing software I had written together with detailed Wordperfect scripts I wrote that automated combining database lookups into legal forms.

No other firms had anything like it. Of course, that changed very rapidly. I have always regretted not having the balls to leave my law practice to commercialize my software - but I had to put food on the table. Nevertheless, computing has been the love of my life to this very day where, in retirement, all I do is tinker with my home network playing around with linux.

TedDoesntTalk · 2d ago
> Even as late as 1978, an informed observer could still consider interest in personal computers to be exclusive to a self-limiting community of hobbyists

WHAT? That was true even well into the 1980s.

WillAdams · 2d ago
The Personal Computer became an accepted, even required business device when IBM launched their PC in 1981 --- at that point, w/ WordPerfect and Lotus 1-2-3 there was a standard set to which folks for the most part adhered --- going into a Compubiz? (blanking on the name) which sold Big-Blue to businesses was a lot different than going to an Apple reseller at that time, or earlier.

A vivid memory was being in a computer shop when a young accountant pulled up in his Trans Am and declared to the salesperson, "I need a Visicalc" --- once it was explained that this was a program for a computer and that one would be needed, the guy was set up with an order of basically one of everything in the store:

- Apple ][ w/ 80 column card and matching green monitor

- disk controller and dual disk drives

- 132 column printer

and of course a copy of Visicalc and a couple of books on using a PC all of which was then loaded up into his Trans Am and he drove off into the sunset --- always wondered how that worked out....

HeyLaughingBoy · 2d ago
Probably worked out pretty well. I get the impression that people tried harder back then: stuff cost more and there was less help available. So, if you even attempted to jump in the deep end, you were committed.

In the late 80's/early 90's I was working for a little electronics manufacturer that also sold Color Computer software. I remember all the phone calls and letters asking for support and there was one lady in particular whose complete address I remembered because she wrote us so often, trying to get her Digitizer working. She was finally successful and pasted a scanned photo of her daughter in a cowboy hat into her final thank-you letter :-)

One of the lessons that stuck with me all these years is that quality of product documentation/ease of use is inversely proportional to the number of support calls I had to take.

After VisiCalc, there were plenty of computer users who were not hobbyists.
acheron · 1d ago
I don't think so. My dad worked for a consulting firm ("Big Eight" as they called it back then) in the early-mid 80s and as far as I can tell his job mainly involved slinging Lotus 1-2-3 spreadsheets on PCs. PCs very quickly infiltrated business starting in the 80s and had already left the exclusive "community of hobbyists".
