Thanks for that, Mark.

I've actually ordered a Mega clone myself - been needing an excuse for a while, plus some of those FET based level shifters which I had not actually seen before.

As well as the task of verifying the PROMs, is there anything more we can suggest looking at on the purely electronic side? The lack of activity on either side of the data bus buffers sounds strange, as does the odd signal on what should be the data buffer 0V pins (pin 10 of each IC).
