Joe,
thanks for your hints, I agree with #1: you confirmed what I suspected.

However, both of the #2 motherboards will not fit into any PC slot, they
are about the footprint of a regular desktop PC itself. I believe it is
some kind of pre-PC computer mainboard, but I was not aware
Ungermann-Bass were ever building something like this. Of course, I had
tried Google with no applicable results.
1) Ungermann-Bass ISA board,
2) Ungermann-Bass motherboard,
#1&2 are both old ethernet boards. I doubt they're worth saving. some of them
have power inverters (produces -8VDC from 5 or 12 VDC) on them so those parts might be
usefull. Hmm. IEEE 488 is a HP-IB port so this is a usefull
card. However finding drivers might be a problem. If you don't need it put it on
E-bay, someone will recognize it and you should be able to a few dollars for it.
Yes, IEEE 488 is HP-IB. But, the port is on a daughterboard that fits
into the #2 motherboards (with a very proprietary plug), so if this
wants to be useful, I'd also need to revive the motherboard. Maybe this
reduces usefulness to the TMS9914 controller chip.
All these boards (#1 Ethernet adapter, #2 motherboard, #2a/b
daughterboards) have "Ungermann-Bass" printed on them, so I am sure who
made them. Only the board with the 68000 CPU is obviously from somebody
else.
I think I'l wait one or two days before harvesting the bigger chips -
just to make sure I won't get punished by a desperate classiccmp
collector for murdering his favourite, rare hardware... ;-)
