Found some more boards that are of no use to me, for the price of dropping 
them off USPS priority ($7.50) you too can own a DZV11, the original four 
port serial card for the Q-bus. They come with a 40 pin ribbon cable and 
the 4 port DB25 bulkhead. (you can also use these bulkheads on the DHV11s 
and others.

Why would you want one? Perhaps to create a period accurate PDP-11/03 or 
PDP-11/23. Or perhaps to experiment with Qbus serial cards.

Why don't I want them? I've got a dozen DHV11's (8 ports) that are just as 
useful and twice as dense).

They are quad width cards. Work well in the BA11 chassis and they are old 
enough that even Ultrix 1.2 knows how to talk to them. You do _not_ want to 
put them in a high speed VAX (like anything faster than a MicroVAX 3500).

Max serial speed is 9600 baud. So they aren't particularly fast either.
