It's not too difficult, although I had to wait until I had a scope fast
enough to get the circuit running properly. It's based on an F628
running at 3.6864MHz (all I had to hand at the time) which does
some simple line controlling and RS232 back to the PC. The
data collection is done by a dividable 40MHz clock driving 32k
fast cache RAM via address drivers / latches. It could use a heap
of improvement, as time permits, and I think it would be worth
something to others as a complete project
