That’s impressive indeed! When I was 12ish I was just struggling with BASIC and PASCAL on PC. No documentation nothing... had to wait a couple of years to learn assembler on an hp48 and later to have a pirate version of Borland C and some books to make sense of the things I would randomly understand ... oh and I loved elite :)
Sounds quite familiar. I was 11 years and struggling with assembler on Atari ST. There was a short series of 68000 assembly basics in a Finnish computer magazine (MikroBitti) and some sources on disk magazines (Maggie by The Lost Boys).
