Less powerhungry, yes. It also takes less space on the Unibus, and is
faster. But I wasn't aware that the DEUNA had any more bugs than the
DELUA. Please enlight me. (I only use DELUAs myself, but I have one or two
DEUNAs lying around).

TUK50 was (is) the name of that controller. I've actually played with a
VAX-11/750 with a TK50 once upon a time many moons ago.

Was there a TUK70 - or was the TK70 for the Qbus systems only?

I don't think the DEUNA has that bug which riddles the DEQNA.
Also, the DEUNA/DELUA loads some microcode when I start using them, this
is running RSX. That microcode is located on the RSX system. Beats me what
it is for, or anything.
Worse (parhaps) is that the device driver for the DEUNA/DELUA don't work
with any Q-bus models, which means I don't have a driver for Q-bus
machines...
Anybody know anything more about this? I really don't care to dig around
the sources here, and also, I don't have the sources to all components.

Yes, Q-bus only. When the TK70 came out, I guess DEC had decided to stop
development of Unibus peripherials.
I very much doubt they sold that many TUK50, or RUX50 controllers.

OK.. Biggie here is that this machine doesn't have a tape drive, just
2 RA92 drives. It used to have a TU81, but it seems to have been junked
Congratulations on getting a /94 with RA92 drives! Condolences
on the tape drive being junked. No ethernet
card either.. (anybody know where to get a DEUNA cheap??)
In the US there are many places which sell used DEC equipment but
I do not know of any in the Netherlands. If at all possible get
a DELUA insetad - less power hungry and fewer bugs. From Johnny Billquist <bqt(a)Update.UU.SE> Sat Dec

this thing. At least the RA92's are quite a bit more 'civilized' than the
RA82 on my uVAX which is more like a howling banshee..
Use less power and are more reliable (also larger capacity I believe) Guess my first
search will be for either an UNIBUS SCSI controller or
a TK50/TK70 controller as I still have some drives for those..
A TK70 controller will run a TK50 drive very nicely _and_ offer
the benefit of the buffer cache (which speeds things up greatly). I
do not know if there was a Unibus TK50 adaptor though. From "Steven M. Schultz"

That sounds a little small. AH, let me go check /etc/disktab on

The RA90 was ~1.2GB:

Hi -

Agree. I'd like to get my hands on a /94 myself... :-)
An 11/93 would be nice too, Qbus systems use less power and make less
noise from what I have seen.
Less powerhungry, yes. It also takes less space on the
Unibus, and is
faster. But I wasn't aware that the DEUNA had any more bugs than the
DELUA. Please enlight me. (I only use DELUAs myself, but I have one or two
DEUNAs lying around).
I know the DEQNA had firmware problems that could cause the board to
lock up under load - perhaps I was confusing the DEQNA and DEUNA.
The later Qbus board (DELQA) was much nicer in the same way that the
DELUA is better than the DEUNA.
