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.
