Off almost certainly means leaving the pin open.

Shouldn't matter that the memory isn't on board, since it's PMI memory.
The real question is whether the KA650 allows the bus arbiter to be
disabled, and provides the interprocessor doorbell interrupt.

Are there KA650 and KA655 manuals comparable to the KA630-AA CPU Module User's
Guide? I haven't been able to find one. I recently got a KA655 (M7625-BA)
with three M7622 16M RAM boards (two M7622-AT and one M7622-AP). I'm hoping
that I can just swap it with the KA630 and MS630 in my BA123. (In the BA23,
IIRC, there are only three CD slots, so I'd only be able to use two of the
memory cards.)

Anyone want to trade anything for a KFQSA (M7769)? It's a Qbus controller
for DSSI drives, of which I have none. A KZQSA would be much more useful
to me. :-)
