I'm familiar with the various DEC Unibus backplanes, but I'm not a LCG
guy. I just wondered it it was in the 11/40 front end. Either way,
with a part numder I might find something on fishe.

That's the problem. ?What he needs _isn't_ a generic Unibus backplane
(technically an SPC backplane), but rather an LP20 backplane. ?The LP20
backplane has Unibus in and out, but is wired specifically for the LP20.
This is the same situation as for backplanes for many Unibus devices such as
the MM11-E, RH11, and VT11; they pass Unibus through but are very
specialized backplanes that aren't useful for anything else.
