The DZ11 I am familiar with is a single card with 8 UARTs. Could
you be thinking of a different serial card, or were there perhaps
two DZ11s?

What I meant was when people interested in cheaper PDP-11s switched
from buying 11/04s and the like (new) went to buying 11/03s and
11/23s without the MMU. Software Results changed from building
HASPBOXes out of PDP-11/04s to 11/23s around 1982 or so, for
example, as the cheapest box that they could use to run the Bisync
protocol engine that preceded the COMBOARD.
