The 11/84 used a CPU board without memory. The memory

It doesn't need a ribbon cable, but PMI uses the CD-interconnect instead
of the QBus, and the memory has to be in a higher slot (physically, that
is; ie a lower-numbered slot) than the CPU. I thought the Unibus
adapter went below the CPU. However, I've only met an 11/84 once, and
that was a long time ago, so I can't be sure about the Unibus adapter
placement.
