These I plan to retrobrite so they look as nice as the other keys.
Cool! I love how detailed and helpful these old documents werekakan wrote: I quickly looked up the TI SN74159N, AMD AM26LS31PC, Motorola SN74LS03N and their respective datasheet and all of them run on 5volts.
Edit: also from the documentation earlier there is a service manual that states the xerox workstations components run on 12v and 5v under RAP1

Keyboard information is sent out in one byte codes unless there is mouse
information, in which case a 3-byte code is used. The keyboard is
asynchronous and operates at 9600 baud. During periods of no keyboard
or mouse activity, the keyboard will send the mouse coordinates back to
the workstation every 400-500 milliseconds. If no byte is received from
the keyboard within a second, the processor will send a reset command
to the keyboard.
The + 5VDC needed to operate both the keyboard and the mouse is
supplied by the lOP PWB through the keyboard cable.
These are Star keys. PROP'S is short for PROPERTIES, which brings up the property sheet (inspector) for the current selection (text, document, etc.) Similar to Mac's ⌘I, but more consistent.
https://github.com/tmk/tmk_keyboard/tre ... r/news_usbNEWS keyboard protocol is a usual asynchronous serial communication. You can receive data from the keyboard easily with UART of micro controller.

Final outcome:snacksthecat wrote: One thing that I wanted to do was retrobrite the two ABS keycaps. I tried to take "before and after" pictures that were as accurate as possible. Unfortunately, I realized after the fact that my camera is set to auto white balance so it might not be a perfect comparison. Nevertheless, here is the results of submerging in 3% peroxide under a UV lamp for about 6 hours. I will probably go for a bit more to even out the color and get it a touch brighter.
