Well, you did ask for "thoughts in the conversion", so I gave you mine.
Sorry if you felt they were unhelpful. I just thought the "conversion"
was basically a no-work. Programming proms is something I have spent
more time than I can count on, and is so routine that I don't even think
about it.

I have a decserver 550 CPU converted to a real KDJ. It's as simple as new ROMS
and one resistor. I also removed the s-box bracket to fit my chassis. Runs BSD
2.11 just fine (RQDX3 disks)

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
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

It's been a while, but
Its a terminal concentrator. I have a load of those 8 and 16 line cards.
They would have fanned out to via splitter cables to back /front panels
with 9/25 way D connectors.
They look in a bit of a sorry state. I would not apply power or plug
into any other chassis.

These are the cards in the DecServer 550. Looks to be an expansion
chassis with 108 ports or so.
Thanks
