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. -- _/_ / v \ Scott Alfter (remove the obvious to send mail) (IIGS( https://alfter.us/ Top-posting! \_^_/ >What's the most annoying thing on Usenet?
