And the story was that the H/Z-89s came with green phosphor screens
so that the Zenith suits could tell the difference between a computer
and a monitor. <grin>

[TELECOM Digest Editor's Note: Actually I had two Z-19's; one had a
green phosphor screen, the other one was an amber phosphor screen. The
green one came first; by the time I got the amber one, Zenith and
Heathkit had added a wee bit of intelligence to the units, such as the
time/date function, and a couple 'pages' of history and a few 'pages'
for current work, etc. Or maybe those chips making all that possible
came from outside vendors. I just do not remember. PAT]
