Ah, thanks for that. The prints for the boards are available, in the
PDP-11/05 Engineering Drawings (on pp. 115-137), but the MF11-L backplane was
previously missing. (The -11/05 generally mounts MM11-L sets in the main CPU
backplane, so the MF11-L backplane is not included in the -11/05 prints.) It
is the non-parity MF11-L backplane (DEC part number 54-09959), not the parity
one (part number 54-10331), though. (My theory is that the non-parity version
can be upgraded to parity with an etch cut, and some added wires, FWIW.)

I have finally got around to scanning the print set for the DEC ME11-L memory 
expansion unit
and you can find it at
https://archive.org/details/dec-me-11-l-core-memory-system-engineering-drawings/

The quality is acceptable given that the office supplies shop where I (DIY) 
scanned them on an A3
scanner only allowed output as JPEG or PDF (undoubtedly wrapped as JPEGs 
inside) so I thought there
was no point degrading any more than necessary with editing the JPEGs to 
another format just to
re-save them. I just bundled the raw scanned pages as-is and it looks fine.

There's also some miscellaneous fragments for the M7050, M715 and M840 module 
drawings which came
with the ME11 set.
