Sweet.. New toy..

The little 50pin connectors are DSSI.
SCSI adaptors typically used the 'centronics' connectors.
Nothing wrong with DSSI.  I believe each drive had state
memory and its own mc68000 processr.  You can log-in
to _the drive_ and inquire usage statistics and other history
from it.  Not necessary, but just another fun thing to do with
VAXes.

There is a set of files called the "dec94mds" that has a file
v4000oga.pdf in it.  That file is the VAX 4000 Operations guide.
http://vt100.net/manx/  says there's 4 copies on-line
