The Atari 800 I had around 1985 or so, I was like 4 at the time, playing donkey Kong and an amber screen

Atari 800 so 6502 1.8 mhz 8k ram cartridge and 5 1/4 floppy. That was my first family computer, the first computer I bought with my own money was a dell T450 Pentium 3 450mhz and an ATI dedicated 3d accelerator card and a 19" Trinitron monitor that I loved to degauss for that satisfying bong noise
