What SCSI controller are you using - MVME320, 327 or 328 ?
Do you reset the MVME177 board using RESET command from 177bug> along with
SCSI bus reset option?
Best regards,

Beautiful clear sunny day here at +9F :)
The SCSI controller on the 68K development system (VMEbus) that I have
cobbled together occasionally hangs after I reset one of the processor
boards (there are four MVME177-005 68060 boards in the VME rack).
The hang then happens when my software touches the SCSI drives via the
ROM'd 68K/Bug I/O primitives and the hang will not go away even after
another reset until I cycle power.
I have never before dealt with SCSI as a programmer - does this sound like
something is configured incorrectly?
There is not much to configure.
I point out that I am not certain that I have the termination resistors
correct.
Thoughts?
I appreciate any advice.
