Dave McGuire and I went over the system and concluded the same, basically
it's either put it there or I can't have an RL02 drive controller because
the NC Grant.  Dave pulled the NC Grant wire from the backplane (where the
NC Grant card is now).

Anyway, I think the RAM card I have installed in this machine is
conflicting somehow with the RL02 attempt to initialize, this is TBD, but I
can't quite boot the machine.
