Tracing the PCB is medatative. And I reiterate the nice things I have to say about the board designer. They silkscreened a bunch of useful information onto this thing.

That gets me to the following:



A full map of the switch matrix for the PCB, with pinouts for the rows and columns.

We're going to skip ahead a bit. I had thought that I might make a video of the conversion process, but for reasons of my own incompetence, that's not happening. As a summary, I desoldered every last one of the vintage MX Black switches that came with the Wyse, and all the chips and components that were attached. Once the board was free, I cleaned up some of the rust from the plate, and rebuilt it with new Novelkeys Box Navies and a Teensy for a brain.
