Sherrif, Rikki, I know what you mean.
I still have a Spectrum 128 somewhere in the house, and it probably still works. Anyone remember these?
Anyway, the beauty of systems like TOS (Tramiel Operating System? I believe it was derived from the Atari boss of the time) are that they are stable, very stable.
Sherrif really nailed it saying that they try to be a thing for all people.
