I'm not sure which rev it is.  It's the 3000A and runs at 16 mhz.

Actually, getting Bell's system was just cheaper.  As some point I believe
that uport will offer a faster compiler and it may then be worth the extra
cost.

I did something similar - since the pid is stored in the lock file, you
can just use "kill `cat $lckfile`".

I was using /dev/lp directly.  Is there an ioctl that will fix this?  My
manuals don't seem to have anything on this.

I finally "solved" this by making additional nodes (same name, but a
different directory).  It works fine now.

I don't think the drive numbers are in the messages.  There do seem to be a
large number of non repeatable disk errors.  Does anyone else get frequent
disk errors?

I'd be very interested in any information on the WD1007, WD1007/WA2, and
the performance of the WD1006 (ie. is it worth it).

The OMTI-8620 sounds like the way to go if it would only work.
