I reckon an ARM7 such as the Sharp 79524 I'm using would be plenty quick
enough. Don't use this one specifically as it had loads of peripherals
you won't need but the Phillips LPC range should cater for your needs.

The LPC line indeed looks attractive bacuse there are many pre-assembled
testing modules available (like the stuff offered by Olimex), and I
think Linux is by now pretty well-suited as a development system.

Another question, maybe really stupid: Skimming over some of these
datasheets I've noticed the absence of any externally available,
"classical" address and data bus. Everything seems to be general-purpose
I/O. Does that mean that I have to implement my own protocol for
addressing external devices on a bus, or can the I/O pins be somehow
switched into "von Neumann" mode?

I'm sure all this will be readily answered by documentation available on
the 'Web. I'm looking.

Thanks,
