Actually, considering they look 'tall' and are labeled as K1, K11, etc,
I'd expect those to be relays. Considering the relays and the size of

Analog Devices. I'd try to
chase that down with them, if possible.
I've seen that shape of board before, but can't place it.

Subject: WTH is this?
Does anyone have any idea what this card is for?
<http://www.classiccmp.org/hp/mds-80/analog-d.jpg> When I picked it up I
thought it was a Multibus card but a closer look reveals that it's (1) too
tall, (2) too narrow, (3) The large connector at the bottom has 100
contacts instead of 86, (4) the narrow connector has 40 pins instead of 60
and it sticks down too far.
Any ideas?
