DMF-32 (and clones) versus DH-11 (and clones) versus DZ/KMC-11

[Doug Gwyn <gwyn>]

The KMC11 is not at all horrid to program, if you use the software
supplied with every AT&T UNIX release since System III.  The source
language is very like C, and about all that one would want to do is
to make some very slight changes to the distributed source code,
which is a lot easier than writing the whole driver.

Most of the terminal driver was put into the KMC11, including input
canonicalization and echoing.

There should be no "Unibus problems" with the KMC11B.  It can and
does serve as a bus master, but so what?  That is part of the Unibus
design.  I used to have a display processor (VR48) that was a second
Unibus master; it worked fine.
