Child of the 80s here. I won a couple of those back when. I got one published by Nibble magazine (Apple ][+ assembly) and one in BASIC got me a free disk at Beagle Bros. I loved 6502 assembly language.
Your comment was a fun trip down memory lane. I'd read Nibble cover to cover, and especially scrutinize Beagle Bros advertisements because of the little one liner programs they'd often include. Good times!
