My dad being in the business, we had an old Mac XL (not a Lisa as I always thought) with a Memory game on, and an MSX with a few games I could barely play. But what I did learn early on was how to work a command prompt, so that was nice. I must've been, like... seven or eight at the time?
Later, we got a NES with a 370 multicart. Of course, most of those were just variations of the others with certain cheats on, like "SUPER MARIO FS" where you'd start every level as Fire Mario and you could swim everywhere. That was about the time I honestly started gaming, 'round ten years old or so? No more than twelve.
Wasn't long until I built my own 286 in my bedroom. Imagine that, little twelve-year old sumbitch carrying a heavy CRT up the stairs.
The rest, as they say, is ROM BASIC NOT FOUND
