In highschool I wrote software in 6502 assembly and Turbo Pascal to send files from Atari through joystick ports into lpt port on pc to transfer Atari games and run them on emulator on pc. I had no idea about protocols so I was using one communication line to signal that there's new data on others. Also pre-internet times.
I also wrote few games on Atari when I was even younger, but since I got pc in highschool I haven't been able to make any decent progress on (let alone finish writing) a single game on PC. Despite writing a lot of software professionally as an adult I never had the motivation, that I had as a child, to go beyond shallow, small experiments for my personal coding.
My Atari 2600 had an odd behavior with the reset switch. Holding it down at the beginning of the tank/combat game enabled your first shot to go through walls. Did you any Atari bugs while you worked on it? Pretty amazing that you could program these without the benefit of searching any internet for answers. (btw, I replied to you elsewhere :-P)
