I stumbled upon someone blog post who did reverse on the ARP 2600, made “corrected” schematics, and PCBs images to transfert/etch. From that I started the project of building an ARP 2600 and also making it a project more modern with KiCAD. The first step of getting the schematics captured is done, intensive reviews are

First thanks for all the patrons, some money seems to have been left over by Patreon and ended up making around ~150EUR, which I spent on a headbump for a second-hand 13MHz RACAL-DANA Programmable Frequency Generator last year. I wanted one for a long time to help doing repair on radio equipment, and my first
