The board in
question is labled:
NSC NS23D
It also has three jumpers near the contacts.
It's a National Semiconductor board. But I didn't know that they
made any as large as 2 Mbytes; the largest NatSemi Q-bus board
that I've ever seen is only 256kbytes. Can you identify the
memory chip type and count how many are on the board?
They have a 9x8 slab of ram on it with one more at the top of the board.
The chips are "TMS 4256-15NL","EHP 8736". The circuit board itself
has
1985 imbedded in the board.
