Once I figure out the memory map that was exactly what I was going to do
while probing the chip.

You could poke directly at the relevant memory ranges and see if a
corresponding peek shows the data

Okay. Thanks for the hints. Anybody know any good RAM diagnostic
techniques for a 102? It's been a long time since I've used a scope in anger on
anything but serial or audio. I'll dig into the datasheets tomorrow and see if
I can gather any clues. A quick probing shows lots of address line activity on
all four chips - mostly just testing that my scope can see these signals...
It's been a while.
Thanks again,
