My father just rescued a Hazeltine 1200 from a scrapheap for me. I know
nothing about these. Could someone give me some pointers to
information? Thanks.

Nice! I don't know anything about the 1200, but I have
a 1500 and a 1421. They are both just simple
terminals, with some fairly basic control functions
What does it look like? Is the keyboard integral or
detatched? Does it look like the 1500/1400 series? -

Now, if it looks like the 2000, you've got a great
score. Those are some interesting beasts. I've never
seen one, but they look like this.

The Hazeltine 2000 was a very early video terminal
(circa 1972).

I have a 1400 (beige) and a 1500 (black) in my collection. I haven't
gotten them hooked up and played with yet. I need to get my terminal
server up and running and then hook up all the terminals :)

Ah-hah. Found a picture of one.
http://www.columbia.edu/acis/history/h1200.html
I don't believe the information on that page is all
that correct, he seems to be describing a Hazeltine
2000 (detatched keyboard, etc). And judging from the
looks of the terminal, model number, etc, I would
guess (guess!) that the 1200 came after the 2000, and
before the 1400/1500 series. Probably somewhere around
the mid 70's.
But, of course, that really doesn't help you all that
much, since I don't actually _know_ anything useful
about the terminal that you don't already. It's RS-232
:).
Very nice score though.

Well the color scheme (black bezel with beige fiberglas case) is the
same as was used on the H1400, a dreadful terminal if there ever was
one. Since my old copies of termcap files don't even mention this
one, even though they do mention the H1000, H2000, H1400...etc., I'm
going to guess that the H1200 isn't an async terminal at all, but
most likely bisync. The indicators and switches next to the main
keyboard area might be an indication of that.
Cheers,
Chuck

Some other people mentioned this the last time the Hazeltine 1x00
terminals were brought up by me :-). However, as somebody who
scrounges around for terminals, Hazeltines seem to be pretty rare,
regardless of the model.

IIRC, they were some of the cheapest terminals available in the mid-
70's. By 1980, they were be ditched pretty fast--they were just too
strange (hex 7e escape ccode really did it). The keyboard was
terrible.
I'm not surprised that not many survived. When the cheap-but-not-bad
terminals like the Wyse 50 came out, keeping a dinosaur like a 1400
just made no sense at all.

New subject: Old Terminals (was: Hazeltine 1200)
Speaking of old terminals.... anyone have or ever use an ADDS 580
(I'm going by memory, it's been over 20+ years since I used one).
Big, heavy, but as I recall had a nice keyboard. I seem to recall
there were white and amber (and maybe green) phosphor models...
I liked the amber one.
In my own 'collection' of old terminals I have:
Teleray TE-10
Digital VT-52
(I'm not bothering listing anything newer than a vt100)

Telerays also seem to be quite rare. I've not been able to find one to
add to my collection :-). As Chuck mentioned, once the Wyse brand hit the
shelf, a lot of these other terminal vendors couldn't compete and died.
There were a *lot* of terminal vendors in the late 70s/early 80s and
most of those died off by the late 80s and the market consolidated to
just a few players. (Also people were shifting to PCs and workstations
from terminals.)
There's nothing more frustrating than finding a nice rare terminal on
ebay and having it packed so poorly that it arrives as a heap of
smashed plastic :-(.

Nice! Let us know the date codes on the chips when you get a chance
to peek inside.

Why does it have to have a processor at all? A number of the older
terminals, both 'glass TTYs' and those with some limited control code
response, like cursor positioning, were built from simple TTL (etc)
chips. Sometimes the artchitecture was something like a processor (DEC
VT5x, for example), sometimes it was just random logic.

one terminal that has no microprocessor (a Basic/4 terminal). I have
a graphics generator that has no microprocessor, but that's just a
display device not a terminal.

New subject: Graphics device with no processor
one terminal that has no microprocessor (a Basic/4
terminal). I have
a graphics generator that has no microprocessor, but that's just a
display device not a terminal.
The classic example of that is the HP1350 'Grpahics Translator' This is a
2U-high rack case that connects to an HPIB bus (I believe there was also
an RS232 version, but I've never seen one), and to an HP vector display.
You send it commands in cut-down HPGL (ASCII command codes and decimal
numbers) and it displays the resulting vectors on the monitor.
What makes it odd is that not only is there no microprocessor inside, but
the circuitry doesn't ahve a parocessor-like architectore. It's just
random logic. BCD-binary converters, state machines, 4K DRAMs, etc.
