Not sure what you expect a "conversion" means. Creating new PROMs imply
finding actual proms, a prom programmer, the code to program into the
PROMs, and then just replace the proms on the card.
Only the last piece will actually require any modification of the card,
and I would expect them to be socketed anyway, so replacing means just
removing the old proms, and inserting the new ones.
The note also mentioned that you might want/need to install a pull-up.
But it would still be an extremely simple process. You just need the
right bits...

I would appreciate thoughts on the conversion of the
processor to normal
PDP11 eproms.
The page pointed to earlier has a mention of that too, but the poster
had access to another "real" KDJ and I am guessing copied that.
I don't have access to any version of the system with appropriate eproms
and would appreciate any pointers to the binaries needed.
As to the condition most of the material is the result of moving it from
where it was stored. It will be totally disassembled and tested before
being brought back up. There is about 5 or 6 large deep freeze (for
reference) sized piles of material being sent for e-waste from the place
that is pretty much just junk material under the weather.
Think of this as a Dusenberg rescued from a barn though.
thanks for all the suggestions and observations.
Next thing to go over is a Sun 4/260 "mini" tower. Gads those were
heavy. Back is still aching from moving that.

Interesting. I thought Tthe DECserver 550 was
merely the big brother in
the terminal server line. But it looks like it is essentially a
PDP-11/53 with 1.5MW of ram, you need new boot roms though. Pretty nice.
Yep.
It's essentially an S-box KDJ11 with different ROMs. I happen
to have a CPU board from one, but not the box itself.
One of these days, I plan to burn "real" PDP-11 ROMs and bring 2.11BSD
up on mine. That and my Pro380 are my only KDJ11 machines.
