Anybody have any docs on the DEC LSI 11/93 (KDJ11-E)?
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.
I am trying to run it in a BA23 backplane and
seemingly geting bus
hangs as is there is something that it is looking for that is not
there!
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
basic functioning.
