MVii and Dilog SQ706a

Today, I play around with one of my SQ706a SCSI controllers, in my Microvax II.

First important point is to get into the „Virtual Terminal“ of the Dilog, to map the connected Drives to the corresponding MSCP Devices which will be presented to the MVii.

>>> i
 >>> d/p/w 20001f40 20
 >>> d/p/l 20088004 80000001
 >>> d/p/w 200000ee 3fff  (200000f2 for the second one)
 >>> s 200

Here are the default addresses:
