Info on the -E is thin on the ground. The User's Manual (EK-KDJ1E-UG-001)
is available online, though, which is a start - it gives info on how to
configure it, etc.

QBUS 11's are pretty resistant to hangs, unless you have an interrupted
grant chain. A simple missing device should give a NXM fault.
I"d try getting the whole system working with another CPU, and then plug in
the -E; reduce the number of unknown variables. Although with memory and
console line on-board on the -E, it shouldn't need too much else for at least
