Anyone know what OS the early green screen Amstrad machines used? I think it was the same as an Olivetti we had - I got it in 1990 when my Dad's company were throwing it out to get Windows 3.0 machines.

I think that is all of them, I've used a few other windows versions briefly, but I'm not listing them as they never got significant use from me.

My first mac had 10.2 on it when I got it, then I upgraded to 10.4, 10.3 was one that I used later when I got another older mac to play around with and I decided it was the best for that hardware.
