>From the EPROM label, you have a Webster ESDI controller that has been
rebadged by Spectralogic.  (Sigma, Qualogy, and DSD also rebadged this same
board with their own labels.)  To get into the WOMBAT formatting/testing
utility on a Microvax II, do the following:

1.  Halt the CPU.
2.  At the ">>>" prompt, type D/P/W 20001F40 (enable Q-bus access to memory)
3.  Then do a "D/L 20088008 80000002" (setup the Q-bus map entry)
4.  Then do a "D/W 20001468 AC" (to have Wombat load the comm program)
5.  Do a "S 400" to start WOMBAT.

Note that if the controller is setup for a different CSR than
the default 17772150, you'll have to use a different number instead
of "20001468" to load Wombat's comm program.

On the Webster/Sigma/Qualogy/Spectralogic controllers, all drives
connected to the controller must be jumpred to different ID's.  To
quote from the Sigma manual:

  "ATTEMPTING TO OPERATE THE CONTROLLER WITH MULTIPLE DRIVES AT THE
   SAME DRIVE ID WILL CORRUPT DATA!!!"

(The caps are there in the text!!!)

If you'd like a copy of the entire manual, get me your postal address.
