Well, thanks for the encouragement... :-}
Always happy to help :-)
In fact, I'm planning to "bodge" a
SCS-RRD40 to work with the
KRQ50... I figured, all I need is just a cable from the KRQ50
to the CDROM's native LMS interface.
I have a number of "SCSI RRD40"s that came from the innards
of a VAXstation 3100 at some stage. They look to be a base
LMSI RRD40 with a SCSI converter board. I expect that my boxed
SCSI RRD40 is the same.
So accessing the LMSI interface is probably easy.
The connector at the KRQ50 end is (IIRC) just the usual
amphenol one that DEC seemed to use on a number of
different interfaces.
So that just leaves the wiring.
Sadly I cannot help there. I've never seen the actual cable
so I do not know the pinout. I would guess that it is pretty
much straight through (or maybe with one logical twist) but
that still leaves a couple of possibilities and I do not know
how much harm it would do to just "try" one.
Maybe you can flush out someone on the list with KRQ50
prints or an actual example of the cable.
Don't forget to publish your findings here if you ever do
try it and it works (or fails .... might as well know
what *doesn't* work!).
