Many thanks to all of you who knowingly (and unknowing) helped me with chips, knowledge and encouragement.
I have a working CC again, but by way of a very weird path.
I recently bought a second unit that was described as junk, and for parts only in the hopes of getting enough bits to make my system work again. When it showed up, not only was the LB in better (visual) condition, but it had the main and video expansion, along with a co-pro installed. Recapped the LB on a lark, and the damn thing started! The memory is bad (I know what a sad chime sounds like now!), but that's easy to fix.
Still leaves me with a pile of troubleshooting to do on the original unit . . .
