It was an Atari 400 for me which my single mom stretched to buy me for Christmas when I was 4 thinking it would help me “learn computers”. I never coded a single line of code on it; only ever got game cartridges.
My uncle had a TI-99/4A though, which lived at my grandmothers house. We would write code on it and save the games we wrote (from a manual) to audio cassettes.
I did end up with a career in IT so I like to give my mom credit for that even if it’s a tenuous connection ☺️
