RE: vME Crate to Q-bus DRQ11 DMA interface problem
    ----------------------------------------------
 
	I have a VME Crate which I am attempting to interface to a 
VAXStation 3200 (Q-Bus).  The "recommended" manner is a module called an
HVR-8217 (made by Creative Electronic Systems - CES) sitting in the
VME Crate connected to a DEC DRQ11 DMA interface in the 3200. 

It appears, however, that the DRQ11 is now obsolete!  

!!!! RUMOURS OF ITS DEATH ARE EXAGGERATED

It is definitely not supported by VMS, 

!!!! CORRECT, BUT THE DRIVERS WORK EXCEPT FROM SOME MINOR PROBLEMS WITH RESET

and may not even be produced by DEC anymore (no one at DEC seems to know, or at 
least they won't tell me).

!!!! NOT TRUE, THEY CAN BE OBTAINED FROM CSS MUNICH
 
Does anyone out there have a similar system? - and if so, how do
you hook up the DMA interface between the HVR8217 and the Q Bus?

!!!! WE HAVE PLENTY OF THESE AT CERN. The CERN-Digital Joint Project PROVIDES 
!!!! SUPPORT FOR THESE "UNSUPPORTED SOLUTIONS" AT CERN.

!!!! PLEASE CONTACT Alberto Guglielmi (CERN::GUGLIELMI on Easynet)
