I have yet to totally grok the -11/44, but the documentation indicates the
slots for memory are memory only (i.e. EUB on the A/B connectors). Are you
saying they are also SPC on the C/F connectors? (If so, ever tried plugging an
SPC device into a 'memory' slot? :-)

If so, that would make it very similar to the -11/24, then - although does it
also have the thing where the data lines are connected from the EUB (connector
A) to the SPC UNIBUS (connector C)? The CPU prints show data from the CPU
going to connector A, unlike the -11/24, which sends data to C - although if
the backplane has the EUB and SPC data busses connected, it would all be the
same in the end.
