Are we talking about ISA-bus computers here? If so the colour graphics
card was a Persyst Bob card, and the bi-sync adapter, if equipped, was
also made by Persyst. I know because I signed them to the contract to
buy those two items. I know about their high standards of Quality
Control because they rejected about 1/3 of my initial shipments!
In 1985, every computer that included a CRT made by Philips was made at
their factory in Ste. Laurent, QC, or so their engineers told me.

Hi all,
Back in the 70's and 80's Philips had a quite popular series of mini
computers called P800, which also branched out to the PTS series and
possibly other.
Could I be lucky to find other list members interested in these
products? I know of a few, but there surely must be others. I'm trying
to collect what is left of the documentation.
My first minicomputer (which I still have and can see from where I am
sitting)
was a Philips P850. I now also own a P851 and a P854 (both with
floppy drives)
and lots of spares.
As for documentation I have the CPU (only) technical manual for the
P850,
the 2 volumes of schematics for the P851 and the preliminary manual
(alas
without the microcode source) for the P854. Some other schematics for
things like the P854's PSU, the 4 channel serial port, floppy disk
system, etc.
User manuals for at least the P850 and P851. And some software-related
manuals, manuals on related machines, etc but I would have to check
exactly
what I have there.

Hi Tony
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?
Thanks
Nico
