From the project

Reverse engineered schematics and code for the Prism Instruments PPS 50 DT power supply

Everything is in a very rough state at the moment but I wanted to put this up there in case anyone finds it useful.

The disassembly is slow going, full of placeholder stuff, and likely riddled with mistakes. I will probably switch to ghidra from f9dasm when 6800 support is added.

The schematic is only partially complete but what is there should be mostly accurate.
