You may be right, I looked through a stack of Televideo manuals I know one
of them was for an 802. Most of the manuals were for terminals but one was
for a computer. The computer looks about 12" tall and 18" wide and has a
CRT on the left side of the screen and disk drive or two mounted vertically
on the right side and it runs CPM. It did have a Z-80 CPU. Does a model
850 sound right? I asked about the computer but no one knew where it was.
That's not unusual for them. Yesterday I finally found a keyboard for a
computer that I bought there over a year ago.
I know know someone that has a heap of old 970 terminals. Is there
anything in them worth saving? They've been out in the wheather so there's
no guarantees on the condition of the parts.

It seems to me that the 802 was a televideo terminal
with an integrated
workstation. These worked in conjunction with a server unit to run an OS
called MOST, I believe, and I have a couple of the server units, the number
of which will occur to me when I look at one again.
These were fairly late technology, using 64k DRAMS and a 4MHz Z80A. The
servers had four or five serial ports using Z80 SIO's and either 10 or 20
MB winchesters to go with their 5-1/4" floppies. They used the
WD1000-series HDC, which used an 8X300 microcontroller (I2L technology,
Harvard architecture) and the WD1000 5-chip set. I always admired the
packaging technology, which was first rate.
I have to believe the workstations were up to the same standard in
convenient packaging. Televideo was late getting into the desktop
workstation market, but did it in a big way with these numbers, as they had
all you could want. The OS was purported, by some users I knew, to be
quite a bit superior to MPM, which was quite established at that time (late
'70's, early '80's).
If anyone is interested in the server units, I can make them available,
less drives, and possibly a couple of SIO/2's which I scavenged years ago,
for the packaging/shipping cost.

Does anyone have one of these? I found a manual for one of these
yesterday
and it looks pretty cool.
