Mystery S-100 computer.

This is from the estate of a friend, Ken Gielow ... a long time programmer (wrote Z80DIS, a great disassembler for the Z80), and magician.
We're trying to find a home for it, hopefully selling it, with proceeds to go to one of his designated charities (not tax-deductible, most likely).

If you have any questions, please email Stan Sieler.

The main buss board is a ThinkerToys WonderBuss.

There is a separate/spare front panel:
spare front panel: from Ithaca Intersystems DPS-1 (2 MBs)

The installed front panel is semi-transparent, so we can see "WMC, Inc." on board #1, which is likely Wameco. (Some Wameco boards: here.)

Front panel (1 MB)

The boards have been seated since probably 1982, forty years.
They do not yield to gentle tugging, and none of them have integrated board lifters, unfortunately.
I plan to update this page if we get better photos of the individual boards.
Top view 1 (3 MBs) Top view 2 (3 MBs)
The box is metal, and has a plain metal top (not shown). The power supply (possibly mounted on a wood frame) is in the chassis, but not really visible in the photos.

The # in front of some is the board number, counting from the front.

#4. board with some EPROMS: CBASIC (350 KBs)
#4 left side of above EPROM board (324 KBs)
#6. Bytesaver board: EPROMs: DISCUS, TRS80 Level II (341 KBs)
#8. printer interface? (266 KBs)

In addition, this unpopulated board is not in the computer (and is somewhat dirty):

memory? (444 KBs)

memory? (back) (422 KBs)

Based on the labels of some of the EPROMs, it looks like it could be a homebrew TRS-80 clone ("TRS80 Level II", "CBASIC"), and may have software for a Morrow Designs hard drive ("DISCUS").

If you have any questions, please email Stan Sieler.
