I contacted the owner, and he sent me some photos.
They me be accessed temporarily at:
http://www.harlie.org/ti990
These are reduced resolution photos that download
in reasonable time. I have higher resolution if
needed.
The system looks to be a 990/10 CPU and a CD 1400
cartridge disk drive in a short pedestal rack.
Does anyone have actual maintenance prints for the
990/10? I looked on bitsavers, and there is a tech
manual with theory of operation, but no prints.

I have the print sets; they came with the half dozen of 990/10 we
got some time ago. We also have some 990/12 (also with print sets) and
990/4.
This is what I have:
- Computer Chassis and Enclosures - Volume I
945421-9701
- Processors and Memories - Volume II
945421-9702
- CRU Expansion and Peripherals - Volume III
945421-9703
- TILINE Expansion and Peripherals - Volume IV
945421-9704
(I think I also have Volume V AMPL Systems... and lots of DNOS docs etc.)
Oh, I see that the schematics *are* on bitsavers in .../ti/990/schematics

Christian, could you look at the print sets that came with the 990/12
and see if they cover the 990/12a or A13 chassis
I have a 990/12a which is a later model. Has a 13 slot cage with the
cards in a horizontal position. The power supply is dead .
I have not been able to find the drawings for it. The power supply
is a single board switch mode supply with only connectors to
the back plane and power in. Very simple looking. The earlier
systems seem the have much more complicated power supplies.

Also, it's unlikely I will do anything with the systems and document duplicates that
I have, so the lot may be available if someone were willing to make a reasonable offer
for the lot in the Bay Area.

I have the docs and prints for the /10 and /12, and most peripherals.
