Thanks for the offer, I have 4 A500s that I can't keep busy now, sounds like a nice system though. I asked how many he had because the poster sounded as if he had found an abandoned warehouse or something.
It's always fun to see how far an A500 can be expanded. One of my next projects is to expand only the fast ram to 8 Megs and run a RAD: drive. I will leave it 'on' always and interface it to something, data-logging maybe. There is something pure about this. Grin
What I need is a source for the Zip ram chips that Supra used in their 500RX. Anyone know of any?
