Anybody here who owns this card or another Ungermann Bass?
I got one but the a*****e seller removed all components on sockets.

I have found some bad photos and the diagrams here:

I think with this support all components can be added. Many are empty on the reference photo too and seem not to be required?
U42 80186
U34 / U35 ROM
U57 (empty or Z8530) - 40 PIN
U56 (82586)
U53 (74LS244)
U65 (502A)
U58 (74LS245)

But I need images of the ROMs to complete the card. Anybody has them? Also a better photo of a complete card would be very appreciated.

Thank you! :)

Oh hey, that's my board!
Sorry about the poor photos, my lighting setup wasn't all that great at the time (I think I was crouching in a corner trying not to wake up my roommate who was still asleep at 2pm or something)
In recompense, here's a couple better ones, and dumps of the ROMs.

I don't know why there's chips missing either; I got this card with no context for $5 from a bin at a VCF.

This may be part of a broadband adapter
Note there is no PHI or bus interface.
I suspect that's what the top headers are for

I'll get some pictures and dump the firmware of the IBM version used in the PC/RT next time I have
access to the machine.
