I was poking about for alternatives to the hefty
KDB50-Q SDI
controller set for MicroVAX to connect up my Emulex SD590 SDI hard

DEC T1003 VAXstation BDA SDI 5015772-01 Disk Adapter to Single Drive Interface
That's a VAXBI boardset. As others have pointed out, the only "microvax"
machine
that these might fit into would be a VAXstation 8000. That's rare and
(iirc) something
of an oddball, so the KDB may not work even in that.
If you have MicroVAX 3100/VAXstation 3100 style machines, they're SCSI.
Although some of the later
ones could do DSSI (if you have the right adapter).
The MicroVAX 3500/3600/3800/3900 machines are Qbus. So with those your
only option
would be a KDA50. A KDA50 will also work with a MicroVAX II.
Turning things around slightly, if you have SDI disks, then your easy
connectivity options
are KDA50 for a Qbus machine or KDB50 for a VAXBI system (VAX 8200/8300
would be
the smallest of these). If you are lucky enough to have a VAX 6000
system then there's
an XMI SDI controller (iirc) or you can add a VAXBI to your system (I
don't recall whether
it happens to have one already).
