Hello,

I'm trying to expand the help files on some of simulators and noticed that I can't find much information for the PDP-8 FPP. I have current documentation but there are no references to the FPP at all. If anyone can point me in the right direction, I'd really appreciate. I'm also checking to see if I can get any relevant information from Bitsavers.

The most comprehensive documentation is the Maintenance Manual:
http://bitsavers.informatik.uni-stuttgart.de/pdf/dec/pdp8/pdp8a/EK-FPP8A-MM-001_FPP8-A_Maint_Sep76.pdf

Chapter 2 has the register info.

Also, FPP-12 documentation, for example http://bitsavers.trailing-edge.com/pdf/dec/pdp12/fpp12/ The FPP-8A and FPP-12 are register compatible. The FPP-8 has a few tweaks but it's generally quite compatible.

If you want any review of whatever documentation you end up writing, I'll be happy to help (I did a bunch of work on the SIMH FPP-8A simulation to get it working and make it compatible with the real FPP.) -Rick
