    Mario -

    OK, what if we only have a later-model VAXstation? We have a 3100/38
(KA42-B), and its response to "T 73" or "TEST 73" is "ILL CMD." I'm trying
good old TEST 75 (the SCSI disk eraser) with the high bits set as above in
the response to RUsure, but I won't know until it finishes formatting and
bad block relocating (sometime later this same life cycle).

    Ironically (old ironically? :) the Model 38 is going out the door
Tuesday as part of an Alpha upgrade (to OSF/1), and then the only
VAXstation we'll have is a 4000/90. Any hints on setting RZ55 bits with
it? (It doesn't know TEST 75 from a hole in the wall.)

    Thanks,

                  Joe Gurman
