Wanted: ICL OPD or Merlin Tonto full schematic

Postby Dave » Tue Apr 18, 2017 5:52 pm

Hi all,

I'm looking for a copy of the schematic for the ICL OPD and/or the Merlin Tonto. I am also looking particularly for the 8051 code from the OPD that replaced the 8049 of the QL. Finally, really would like to see the PCB of a OPD microdrive.

Any assistance gratefully received.

Hi,

Do you still need this info? I have copies of schematics but they are scans of photocopies so can be difficult to read in parts.

Just the 7 scans of the main board add up to 500K between them.
