If those 6502s can be got reasonably cheaply I'd be interested...

I thought you might - I have never seen them around.

If you've got an ARM, I wouldn't bother emulating a 6502 - you would have a
job getting it up to speed. Just use it native - there's plenty of Arc
stuff around, & I bet a fair bit could be botched onto one of these.
There must be tons of unused ARM2s about after everyone has upgraded to the
ARM3. If anyone knows of any lonely ARM processors I'd be interested...


If you can get a 10-15MHz 65C02 I reckon by far the best bit is to soup up
a second processor like someone else wants to do. Sod messing around with
hardware emulation - after all, you don't really want to play Exile at mach
3 do you?? A fair bit of stuff (esp. useful stuff) will already work over
the tube. I haven't looked in detail at turbo-charging a second processor,
but I reckon it would be relatively easy. (esp. compared to doing it direct
to a Beeb!)
