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.
2a) "MODEL 6402A": 2 * RS232, female 25-pin
sub-D connector, labelled
"SERIAL PORT 1" and "SERIAL PORT 2"; 1 * IEEE 488 (labelled so),
real-time clock (guess so, there is an OKI MSM5832 chip, a crystal, and
a 3.6V NiCd battery). Other chips: Z80ADART, Z80APIO, TMS9914A (IEEE488
controller), Z80ADMA.
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.
2b) "MODEL 6401": 4 * RS232, female 25-pin sub-D connector, labelled
"SERIAL PORT 1" through "...4", then "PARALLEL PORT 5" and
"PARALLEL
PORT 6". Chips: Z80APIO, 2 * Z80ASIO.
No HP-IB port but based on the number it's probably made by the same manufacturer.
Have you looked to see it etiher of these have an FCC ID code? They should. If so look up
the manufacturer on the FCC's website.
3) Qbus-like board, supposedly a CPU, handles made by DEC, board is 4
slots wide, labelled "PCS" (is that PCS CADMUS?), has Motorola
MC68000L10, 4k SRAM (2*6116), 16k EPROM (2*2764), clock chip (MM58167),
battery. Between the handles, there are two 40-pin 3M connectors (Berg
style). The EPROMs have stickers saying
MINITOR MINITOR
R900.123 R900.123
E9 2.200LO E10 2.200HI
Any hints? -
No idea.
In case you want to trade: I am still looking for a sound
card for my friend's IBM PS/2 (Microchannel). I
cannot buy one of those
currently offered on eBay because they again won't ship outside U.S. -
darn!
Try e-mailing the seller and asking if they will ship outside the US. Some will despite
what their ads say. If you can't find anyting let me know and I'll try to pick up
a surplus one for you. However it won't have docs or SW and that stuff might be hard
to get.
