The LP20 backplane is DEC p/n 54-11704. The complete
backplane assembly
is 70-11590. The complete LP20 wired assembly is 70-11427. IIRC, Rich
included those part numbers in his original request. The LP20 does go
into an 11/40, but only in a KL10 system. The backplane doesn't have a
model number (e.g., DD11-somthing), since it is only a part of the LP20
and not used for anything else.
Actually, the LP20 can also be used in the Unibus on a KS-10 system.
Unfortunately for us, none of our KSes have an LP20.
