Hi gang and Happy New Year,
It's great when you can rummage in one of your own piles and find something
new... (Thanks Alzheimer's) Where'd that come from... ;)
Anyway. I found a TI TM990/101MA card that's about 11x6 inches and can be
seen at:

I guess this came out of a 990 mini but it looks like everything is there to
use it as a sbc. It's got jumpers for terminal/modem,bank,ram,eprom select
and a few more. Google and dogpile didn't turn up anything and I'm looking
for the pin specs for the connector edges, power requirements and any other
info anyone might have.
Also, while on the subject.... I have an extra TI TM990/U89 that I'd like
to trade for a TI TM990/189 with someone in a complimentary position.
Email me off list if interested.
Cheers

Well, there were things such as the 990/602 development system which used
these 100 pin boards. The 990/4, 10, /12 use a different physical bus, and
I don't think the TM990 bus supports TILINE. CRU, yes. The boards for 990
minis have two fingers instead of the single, 100-pin, finger of the TM990
cards.
I have a VPU200 programmer for the 5TI sequencer which uses TM990
boards. I don't have any specs, manuals, or software, though.
The Nov. '82 issue of Home Computer Magazine has a description and a few
minimal photos of the 990/602. It's archived at
