I've managed to acquire a Hall Effect keyboard (and have a working NKRO USB converter, that can even toggle the LEDs). This keyboard has virtually no branding, other than the Honeywell circuitry inside.
Honeywell didn't help me when I asked them (unlike with the Bud Keypad).
However, over the past couple of days, I've found some neat information about the keyboard that points in an interesting direction.
The connector was destroyed when I got it, but is a type of RS-232 like.
And unfortunately was missing 2 keycaps when I got it.
- Patent for this exact keyboard shell, and layout (including the point where the cable comes out of the keyboard and rubber stoppers) http://bitsavers.org/pdf/convergent/pat ... _Oct80.pdf
- That patent is registered by Convergent Technologies (makers of CTOS)
- Convergent Technologies was later an OEM for Burroughs (P20 Line):
- More information on what's in the P20 line can be found here: http://www.faqs.org/faqs/computer/system/unisys/ctos/
- The P20 line was similar, but not quite the same (oo the one below is Cortron)
- The cord can be seen from here http://www.computinghistory.org.uk/big/ ... rkstation/
- This brochure shows a keyboard very similar, but not quite the same (Burroughs styling) http://bitsavers.org/pdf/convergent/man ... _Jun82.pdf
- Notice the LEDs, and Layout, this all points to the keyboard being used for CTOS (Convergent Technologies OS)
- Now, Burroughs was the largest OEM for Convergent (not the only, if someone can answer who the others were, that would help!)
- Unisys (which was formed from a merger of Sperry and Burroughs in 1986) bought Convergent Technologies in 1988 (and was almost bought out by 3COM in 1986)
- From some more reading it looks like Bull was another OEM target for Convergent, but I haven't looked into that connection yet.
