All:
I'm repairing a few S100 memory boards and I'm having trouble
crossing a memory chip on the SSM MB7 16k board. The chip is an NEC UPD410D.
I have D5101LC1's "in stock". Are these equivalent?
No, not even close.
UPD410 is a fairly fast semistatic 4kx1. 5101 is cmos 256x4.
What memory board has a upd410 on it? Very unusual.

The board is a Solid State Music MB7 16k board. I have (at least) one bad
chip on it.
