I have made adapters for individual Cherry MX and ALPS SKC keys to 0.1 inch spacing. They allow for 0.75″ spacing by rotating successive units 90°. For the Cherry MX, a matrix diode can be installed either in the switch (through hole) or on the breakout board (surface mount); the ALPS board only has...

Unique USB PIDs available for open-source projects

Of possible interest to those with input device projects: pid.codes has a VID issued before USB-IF started contractually forbidding sub-allocations, and is providing PIDs for open-source devices.

It likely is the fact that the keyboard is behind the built-in hub. If your BIOS has a setting for PS/2 or “legacy” keyboard support you might find that disabling that makes it work.

The successor machine, the ‘Daybreak’ Xerox 6085 / Xerox 1186, was introduced in 1985. It had a more PC-ish layout, and ALPSy key switches, including some funny skinny ones for the upper function keys.

The pale yellow switches used for the function keys are heavier than current MX Grey switches. Aside from the text, the only difference I can see between the Cherry marked and the HCP marked keys is as the corners where the two halves of the switch case join — the HCP-marked keys have plain rectangl...

I think in total the board will be about 40mm max high, including the connector depth. If anybody has a Displaywriter and is able to tell me, please let me know.
