Very cool! I had an MC-10 when I was a little kid. It was my first computer, and I didn't know anyone else who had one. I didn't have the book with this Arctic Adventure program, but I had another book with an adventure game you could type in. [1] I stayed up past my bedtime and spent significant time typing it in. However, after typing in much of the program, I encountered my very first "out of memory" error. I was astonished that 4KB of RAM wouldn't be enough, and that I was going to need a better computer!
I clearly had the wrong book for that computer. ;)
