I believe you just need to bump the memory to 24kw... from IIRC 16 or
was it 20...

I don't think it cared how many memory boards you used. The original
machines used 4mb of memory on the LSI-11 cpu board... I think they had
either 12 or 16k added on the later ones used the half height LSI/2
boards with memory on a different board.

The 11/785 required more memory for the console diagnostics and boot and
more wcs on the 11/785...
