I’m looking at getting this QM2000 up and running and as a software task, dissasembly of the ROMs is the fist stage. Looking around, the ROM images don’t appear to exist on-line due to the QM2000 being a rare beast. The EPROMs on the GM813 Z80 board and the GM812 Intelligent Video Controller were dumped. Using Claude-Code to perform analysis on the disassembled code, it was able to produce a comprehensive description when combined with the available hardware and software documentation available for the boards. Existing versions of the monitor code were compared to verify the disassembly and analysis was correct.
The monitor ROM for the GM813 was found to be an early version of the SIMON Monitor specifically coded to use the GM829 Disk controller.
The output from the disassembly is available in my QM2000 Github repository.
