A while back, I posted a message about a mystery board that came with
my VAX-4000/200 manufactured by a company named Talon. This board has
one 15-pin connector, a couple of 32x8 SRAM chips, a 68K CPU, assorted
logic chips, and a couple of chips that I can't identify, such as:
- Rockwell R65NC22J4 11484-39 9244 94314-3 - is this just a Rockwell
version of a 6522 interface chip?
- (unknown mfr.) 9206 SC11290CN
There's one area where a second, much smaller, circuit board is
attached to this one with chips between the two boards; however, there
are many wires soldered between the boards holding the two boards
together, and I'd rather save unsoldering them all as a last resort.
Any thoughts on what this board might be?
