Preserving hardware designs

Show key headers only | View raw

I've been on a bit of a kick lately to document old hardware in KiCad. 
Think of it as a smaller-scale version of bit-preserve, which tends to have
schematics but not PCBs:

https://github.com/baldengineer/bit-preserve/

(FWIW, I've contributed the EZCGI to bit-preserve:
 https://github.com/baldengineer/bit-preserve/tree/main/Apple/Peripherals/ezcgi)

Here's what I have so far:

EZCGI (from a Byte article):
  https://gitlab.alfter.us/salfter/a2-9918

ALF MC16 and MC1 (from PDFs in the Internet Archive, IIRC):
  https://gitlab.alfter.us/salfter/ALF_sound_cards
  (the MC1 PCB was based on the original layout in the documentation)

Microsoft Softcard (also from a PDF in the Internet Archive):
  https://gitlab.alfter.us/salfter/Microsoft_Softcard

Willegal Brain Board (from the original website):
  https://gitlab.alfter.us/salfter/brainboard
  (PCB based on the published gerbers)

Each repo provides at least a schematic and PCB layout that'll open in KiCad
9 (the older ones might open in KiCad 7).  A PDF copy of the schematic, a
STEP rendering of the PCB, and gerbers are also included.  Software (source
and/or binaries) has been gathered up for some, but not all.
