I'll be showcasing the design of a (originally) MOS 6502 based PID (proportional-integral-differential) control system. This system has been in productive use until a couple of years ago in the mechanical engineering department in the HAW Hamburg. The purpose of the system was to educate students.

The system is equipped with DAC, ADC I/O functions, CPU, and a variety of interesting controls. This is a multi chassis system, that used to fit in a standard 19" rack.

I'll chronicle my journey to survey, inspect, and get the system into operational state.
