	Here at the Plasma Physics Department of Sydney University we are currently using a
MicroVAX II to acquire data from our tokamak.  This involves interrogating our CAMAC crates
to obtain data.  We are using part of a commercial package called CAMVMS v 2.1 by Sunrise
Software as well as two CAMAC crate controllers made be DSP Technology.

	I would like to know whether anyone out there has used this software and if so whether
it runs under VMS 5.4-1.  Currently we running VMS 5.2 and would like to upgrade to VMS 5.4-1.
Is this possible without upgrading CAMVMS as well?

	In addition I would like to know whether anyone can turn off their CAMAC crates without
causing their MicroVAX to crash.  At the moment sometimes we can turn off the crates without
crashing the MicroVAX and when we turn the crates back on they're left in some unknown state
despite the fact that the software says that everything is okay and that the CLEAR and
INHIBIT lights on the crate controller flash when told the appropriate commands.  
	
	If anyone out there has experience with CAMAC crates on a MicroVAX I would be grateful
for some advice.  Has anyone had similar problems?
