OPD: Computer One floppy interface recreation.

Over the last week or so I've been using the information on the RWAP web pages to reverse engineer the Computer One floppy disk interface for the One Per Desk/Tonto.

I've now got a schematic from tracing all the traces on the PCB print outs and have created a Mk.I PCB design and sent it off to be manufactured. The PCBs arrive on Friday and I have all the chips...

I thought that the ROM image was on the RWAP site but... bother!

Does anyone know where I can get a copy of the ROM image?

The project is rather dead in the water without it.

Thanks to various people in the community, Stephen has gone on to get a working clone of the Computer One Disk Interface for the ICL OPD.
