I started in 1981 at 11yo with a ZX81 writing games in BASIC. In 1984 at 14yo I was cracking games on Amstrad CPC6128, Z80 assembly. At 18 in 1988 it was on PC in DOS (8086). Yes I installed Linux 0.99 on my 486 PC in 1992 or something.
Never touched an Apple device.
Great! Oric-1 was not super popular, I don’t know a lot of people who had one, Atmos a little bit more, but it was when C64 and Amstrad CPC were king, then ST and Amiga.
