Between that and reams of green bar to use at home for "artwork" I found my fascination with computers. Didn't hurt we had first generation IBM PCs and before then my father had about everything heath kit put out.
I would skip school and hang out in the Terminal Room at the local college, playing games and writing programs. I never did finish High School, but I learned what I wanted to do when I grew up. Man I loved that machine.
The author mentions the lack of ability to renumber the lines in a BASIC program, but I'm quite sure there was a RENUM command that would do that.
In 1976 we got ADS (CRT) terminals in the computer lab, and once I figured out ESC-sequences, I had a shoot-em-up space ship game going. God I wish I still had the source code for that. :(
If the Klingons beat you, you'd get this disheartening message, which I remember to this day: "The Enterprise has been destroyed. The Federation will be conquered. You are dead."
I also remember playing a car racing game on the same machine, and also a game about landing a spaceship on the moon (which, a few years later, I created a real-time version of on a 6800 microprocessor in machine language). But the Star Trek game was definitely the best one.
