I bet you're going to be disappointed in the TI chassis, Joe. TI made (back
in the '70's) a line of their microcomputers which used a connector and a
card form-factor like the S-100, sort-of, but which wasn't S-100. One easy
way to tell the difference, I believe is that the TI system, which I never
inspected, hence can't say for certain, used a global power supply rather
than the s-100's on-card local regulation. Their power and other supply
leads were in different places, too.
Let me know if I'm wrong, Joe, as I hope you're getting something you can
use, but something tells me . . .

Went to another one this morning. Didn't find
much except three Lisas
(two Lisa 2s and one Lisa 2/10), two HP 715/50s, two Zorbas and a *NICE*
S-100 chassis made by TI. I managed to get the L 2/10 and the Zorbas.
Pictures and questions to follow.
Joe
PS the HPs are still available if anyone wants them.

Dick,
RATS! I think you're right! I just brought it in and checked. The slots
are wider than S-100 and the card sockets are offset to one side so S-100
cards hit one edge and won't go in. It also has a switcher power supply so
it is regulated off the cards. Too bad, it is really a nice box. I may
modify it back to S-100. Anyway what can you expect for $3?
Do you know anything the TI computer? Is this worth leaving as is in
hopes someone can use it or should I use it for a project box?

I am just curious what the size of the slots are. I have a couple of cards
that I thought were S-100 when I got them, but they are a bit narrower than
an S-100 card, and the fingers are wider. The dimensions of these cards are
8 3/4 " wide, 4 1/2 " high (excluding fingers), 7 5/8" finger width with
5/8" to the edge of the card on left side (component side up) and 1/2" to
the edge of the board on the right. The one I just grabbed says "638493
Digital Timer" on the solder side of the board.

Marvin,
It looks like the cards for this one are 11" wide and about 6 1/2" deep.
The fingers should be about 6 1/4" wide and are 1/2" from the left side. I
don't think you're card will fit this. The card is marked "Assy No.
991632-0001" and (in big letters) "TM 990/520".
