Matrix layout is based on info from this article.
Magnavox Videowriter keyboard conversion project: direct connection of Pro Micro to the matrix.
Make example for this keyboard (after setting up your build environment):
make handwired/videowriter:default

Initially left and right Shift keys are connected in parrallel. You need to cut the traces from right Shift (switch 62) and wire it to column 2 (switch 65, right pin) and row 9 (switch 71, bottom pin).
SN74LS145N IC (BCD-to-decimal decoder, drives matrix rows), NEC D8049HC IC (MCU, drives matrix columns) and resistor array need to be desoldered from the PCB. You need to shorten the 4 diodes (D2–D5) in the bottom right corner of the PCB (solder a wire between their pins). I've also removed two electrolytic capacitors and some ceramic capacitors just to free an additional space.
Optional: add diodes between each switch and corresponding row for NKRO. If you choose not to add them, create config.h
file in your personal keymap folder and add #define MATRIX_HAS_GHOST
to it.
Suggested mount position for the Pro Micro:
Compile and flash the firmware. Use matrix debug mode if something is wrong.
