I have another card I can't identify:
It's a Q-bus card; in copper on the front of the card it's marked
"BSW-Q". on the back, it's marked "4522 111 89361". On the front,
there's a sticker that reads "4522 117 0825" and "1996830". I
think
the latter might be a date code. The 4522 numbers look suspiciously
like 12NC numbers, which to me suggests that this is not a DEC part
(maybe Philips?)
