The performance of the DZ11 is not good. It did an interrupt for every
character, just like a DL11. The Able DMAXes blocked until a carriage
return and then did a DNA, IIRC.
Not sure about the DH and DHV11 - its been a long time. We used Able
DMAXes on the Canadian NAPLPS system, named Telidon, but that was back
in the 1200/300 baud days!
However for vintage computer purposes, that's probably not a concern.

Being lazy admittedly but can these be used for single serial interfacing?
They will not emulate a DL11 or any similar single serial port.
You don't have to use all 8 ports on the DZ11 card but you still need
the right software driver.
That said,it would be a pity to scrap these. Surely all Unibus cards
are getting hard to find now.

I have a box here of 14 DZ11 Unibus 8 line serial port interfaces. And I
have no clue why I have them.
Anyone need some? Otherwise I'll Ebay/recycle them.
