/**************************************************************************
|

|
||||
Skeleton driver for MDT 60 and related Zenith terminals.
|
||||
|
||||
MDT 60 was designed by Zenith for use with Morrow's Micro-Decision
|
||||
computers as a low-cost terminal with limited features. It appears
|
||||
to be a stripped-down version of some previously designed terminal,
|
||||
with the auxiliary port omitted from the Morrow version even though
|
||||
the schematics published by Morrow include it. Morrow's schematics
|
||||
also include the same keyboard used by the Z-29, though the actual
|
||||
keyboard found with one unit was different.
