I have thrown together a hard disk subsystem for an LSI-11/23 system.  I have
an RQDX1 controller connected to a bare RD52 drive.  I think I have all the
signals wired and satisfied.  I am trying to use it under RT-11 V5.1 with the
DU handler.

When I run diagnostics on the controller, I receive the following message
(possibly paraphrased):

	Initializing controller
	SA Register not as expected for step 1 of initialization
	SA Register = 005500

I have no documentation on MSCP.  Can anybody tell me the meaning of that
status value?
