Hi,
for a planned exhibition, I am thinking of restoring two of the
machines to working state again that are in storage here for decades:
- A TI Explorer ("Sperry" labeled)
and
- A Xerox Star (no idea if ours actually ran Interlisp or one of the
other OSes for the Star/Dandelion)
Awesome. I hope there will be online coverage of the exhibition.

Some things I could not find so far are the mouse and
the console
cable for the Explorer. It seems that the mouse is related to
MouseSystems optical mice used on older Sun/SGI systems (but the
interface might be different?). The fiber optics cable for the
display (TI part number 2233200 according to the field service
manual) might be another problem
- if you know any details about this, I would be very interested...
This is the same part # listed for the 990, and I would think, lacking
documentation on them, the BS600 and BS800 machines, if using
the CI404 comm board. I don't know how common those were. My college
only started using them after a lightning strike took out some machines
through one or more serial links, iirc. But that may broaden your search.
From the CI403/CI404 manual
(http://bitsavers.org/pdf/ti/990/datacomm/2263897_9701B_CI403_Nov83.pdf):
2233200-0001 Standard duplex fiber-optic cable, 15m
2233201-0002 Fiber-optic extension cable, 60m
2233201-0003 Fiber-optic extension cable, 150m
2233201-0004 Fiber-optic extension cable, 300m
2233210-0001 Converter module kit, includes: Converter,
Power Module, and Power Cord.
The extension cables include a connector for connectin 2 cables.
I may have some more information on the mouse and maybe some cable specs
soon. Talking to some people who likely know.
