The source code for the FPP8-A is available - I retyped it while trying
to debug the SIMH FPP code.
Getting that source into a binary is a exercise for the reader. :)
Apparently the compiler for this ran on TOPS-10.
The maintenance docs for the FPP8-A give enough information to reverse
engineer the programmable bits.

Too bad we probably can't get the damaged board to image the PROMS and
programmable parts. Thanks Vince - I knew about the RX emulators but
not the serial disk
- that sounds interesting. Is there any documentation on that - I
had a look at the GitHub but seemed a bit sparse.
I can imagine the FFP8/A is hard to find and replicate. I can
probably use emulation - but its nice to check with real hardware.
This is probably not the right place to link the youtube video of the
guy that destroyed a FPP8/A set to recover the gold on the
PCB-fingers...
I do have a rather complete 8/A, with RL01 ad FPP8/A. Alas no sockets
inside so the PROMs cannot easily be read out.
