OK, so we already had a dump of the M9301-YA ROMs, but were (apparently)
missing the others?
So I fnally got one of my UNIBUS 11's running, and whipped up a small program
to dump the ROM contents, and now have the -YB, -YF and -YH ROMs dumped. I'm
in the process of disassembling them now.
(If anyone needs the contents in binary format, to blow new ROMs, let me know,
and I can probably produce them if you give me the details on the format you
need the data in.)
Does anyone have any of the others - YC, YD, YE and YJ?
If you're not up to dumping them, I can send you my small program (currently
in .LDA format, but I can convert it to a script - it is not very long at all
- for the console emulator in the M9301 series), which will do it - it
produces packed octal output, 8 words/line, so a very small output.

I also have a YF card. It came from a PDP-11/10 and was sitting in location
slot 3.
I put it into my NC and there were no smoke coming out anywhere...
I could access the contents but it didn't run very well. So either the CPU
is still bad or the PROM contents are bad.
Could you please direct me to your YF dumps so I could compare? Intel HEX
would be fine.
If you also have done a disassembly that would be very interesting.
Thanks!

Do the M9312 roms help?

Unfortunately not. They are entirely different. M9301 is four PROMs that
provide a 16 bit word but M9312 is four boot ROMS and one console emulator
ROM that are are separated. There are logic that converts the unibus
transaction into many 4 bit transactions. Thereby one can easily plugin
another boostrap by just changing a PROM. With M9301 you had several
different M9301 module, YA .. Yx
