Actually depending on OS and general usage the critical factor for 
the DEQNA was not rev but, is it functional at all?  Most of the 
DEQNAs I've touched and used either worked or were dead, rev was a 
minor issue save for certain OS support issues.  One of the REV 
issues was that the more reworked versions tended to have more 
failures (IE plain old dead) resulting from greater amounts of 
handeling and use/abuse.  For Q-bus 11s the DEQNA was an 
acceptable device.  DELQAs while nicer were scarcer.
