4 Microcontrollers first breadboards with PIC18F877, later 7 algo_pic controllers with PIC18F877A driving 88 keys, gets an realtime firmware written in PIC assembler and needs a parse logic to be driven by the host computer. Here the first layout is documented for historic reasons.
microcontroller software for Autoklavierspieler
firmware for the microcontrollers as mini OS, developped for algo PIC, Escher with is implemented in Mikrocontroller
A first state machine for the prototyp, documented for historic reasons and debugging
