Awesome. Love it. I'm guessing the language was BASIC? Do you still have the book?

Lol. That rules the world. Idk, I'd have to look around. Actually, I think I might. The Vic-20 came with basic pre-installed. I don't know if installed is the right word, there really wasn't enough ram to install anything. I remember having all my programs "installed" on cassette tapes. I can't remember if I had to manually load BASIC or not, I don't think so.
Here's a good story, though. I don't know if you remember, but there used to be this magazine called COMPUTE! Yes, with the exclamation point included. In 1982, from what I remember a good number of the articles were hobbyists publishing programs for the Vic-20 and perhaps some other similar builds. This was before the IBM hit big. I actually wrote a video game called "Blitzoid" that I submitted to Compute! that they accepted for publication and paid me, get this, $175 for. Not bad for a 14 year old. I thought I was going to be the next whiz kid (which didn't happen)
In any case, this game had an, admittedly, crude resemblance to "Defender," and, although I'd like to accuse them of ripping me off, it looks as though Defender came out in 1980. So maybe I'm the culprit. The interesting part, though, is that I initially wrote the whole program in Basic, but it was too slow. I found that there was one subroutine that was the issue, one that was repeated many times to move the "ship" up and down the screen. My remedy was to write the subroutine in machine/assembly language. But guess what, I had to buy another one of those 30 dollar cartridges to do it. Lol. That was a proprietary ROM chip, I believe, so I just couldn't go to radio shack and buy it.
Whatever, the case, I was blown away at the difference it made, that subroutine actually made it a fun, playable game. I remember spending a lot of time on it trying to tighten up the code, and did some creative things, which is why I think Compute! bought the code.
By the way, I don't think they ever actually published the article. I contacted them several years later and they said at that time they were just buying up a lot of the submissions for use in a special video game issue that never went to press. Oh well, I still got the $175, so that's cool with me.
