FYI, that "unpopulated board" is not and never was S100, and has clearly
had some told contact fingers cut off. Perhaps used as a source for
parts at some point.
You might want to join and post this to the "s100computers" Google group.

Hi,
I have a mystery S-100 computer that I'm would like to sell, from the
estate of the late Ken Gielow (author of Z80DIS, a great Z80 disassembler).
The proceeds will be donated to a non-tax-deductible magic group Ken was a
long-time member of.
The computer is located in Cupertino, CA (aka "the heart of Silicon
Valley", in the S.F. Bay Area). (If reopened, you can combine a pickup
with a visit to the Computer History Museum in nearby Mountain View, CA! :)
This would likely be quite expensive to ship. I'd guess 30+ pounds.
Photos and some info at:
www.sieler.com/ken_photos
Some of the hardware (also listed on the above page):
ThinkerToys buss
unknown semi-transparent front panel
spare/uninstalled Ithaca Intersystems DPS-1 front panel
10 various boards inside
metal case (heavy)
There may be manuals on some of the boards and/or the Ithaca, but I'm not
sure yet. (They would be included, if they exist.)
I wanted to take photos of each board, but having been seated for about 40
years, they don't come out if I tug gently. None have integrated board
lifters, unfortunately
(I tried a boroscope, but could not get useful photos.)
Based on the labels on some EPROMS, there's a chance that it's a homebrew
TRS-80 clone, with both Level II BASIC and CBASIC, and may have Morrow
DISCUS software on it.
We're looking for an offer on either:
- the Ithaca Intersystems front panel;
- the computer with all the boards
or both.
Suggestions welcome, thanks!
