As a kid I had a hand me down 286 from my uncle with QBasic, and my only guide the terse help menu. I made so many cool things with that PC through trial and error. Unfortunately my curiosity was not limited to software and I disassembled it destroying it in the process. It's long gone.

I have a feeling my Minecraft infused 7 year old would be immediately bored of it anyway but I wish I still had it to give to him.
