Quite the resource list, Don! You should put in links to the Adventure game you wrote for the C64 Logo, and we listed you by name and age.
The assembler was already chosen, probably by Steve Hain or Gary Drescher. I believe it was CROSS. It annoyed me that I would get phase errors if I edited during the first pass which was like 10 or 15 minutes at night so I wrote a one-pass assembler in MacLisp, but it was slower to finish than the first pass of CROSS so I translated it to Logo and Hal said to put it on the utilities disk. I can't remember who added .output and .input but Logo had had them before the Apple II, I think 11Logo had it.
So CROSS made you so cross that you crossed the line by rewriting it in MacLisp, then double crossed it by rewriting it in Logo itself!
Logo Adventure for C64 Terrapin Logo
When I was 17, Terrapin published my first commercial code on their C64 Logo utilities disk: a Logo Adventure program, a simple non-graphical game that showed off Logo’s list processing and functional programming capabilities.
