I have bought recently a bunch of ICs from 8080/8086 computers (mostly peripherals like PIC, I/O, Timers, memory) for next to nothing and i am trying to build a "retro" synth. It is way more fun and challenging than arduino or esp32, and not really complicated! A lot of instruments of the (Roland Juno, Oberheim Matrix 6, Akai AX-80) are using these chips too, so when in doubt i can take a peek at the schematics and move on with construction.
