The manuals you mention, don't ring a bell.
We have now more-or-less rejuvenated a PTS6813 aka P857, although
without the discs.
Furthermore, we have the parts to build a P852 from spare parts.
In order to test things, I've developped a simulator and assembler for
the P857, although without floating point and I/O processor, as I have
no documentation for that, so maybe I can harvest something from the
documents you have. Are the mailable, or do you need to scan them first?
