Does anyone recognize this card?
probably MIL-1553B (1mbit network used in aircraft)
Any vendor? Huntsville Microsystems made interfaces.
Try googling for "1553B unibus"
Haven't had to deal with that stuff in 25 years.
Please check if the multifunction board (M7096)
in the /44 for boot proms
that aren't on Jay's M9312 page.
The card looks like this:
