thanks for the info guys....i know very little of the Acorn machines. my total experience was in about 1985 at school on the bbc b micro! and after that i was Amiga mad up to 1994 when the PC an Doom won me over!
Now im completely anti PC or more anti windows to be honest and use Apple these days, so much better than microsoft junk - the hours of my life that have been lost re-installing windows 95, 98,98se,Me,2000, xp lol !!!
Anyway i was staggered to learn the acorn machines where 3 or 4 times faster than the Amiga .....i always suspected the A500 was slow in 1987 to be honest!
