A guy on ebay is selling something that looks suspiciously like the
monitor portion of a terminal, but he is calling it a Hazeltine
'computer'. I asked him if it was a terminal and he responded saying:
"Its a computer, not a monitor."
Either he didn't understand my question (I didn't ask if it was a
monitor, I asked if it was a terminal) or he had a brain-fart and
typed "monitor" instead of terminal in his reply.
The item is #300053801044 and has a detail photo of the model plate
where it says model 1DTD155463. On the lower left rear is what looks
suspiciously like two DB-25 style connectors, presumably one for the
host and one for a printer.
So, did Hazeltine ever make a computer or did they only make terminals?

the Hazeltine 2000 terminal had a huge keyboard, with a couple of neon
indicators on it, and
you could kill someone with the keyboard box.
The keyboard attached to the read with a db-25, so this box may have one
connector for that.
The other thing about this vintage of Hazeltine is that they used core
memory for the display
memory, so there is a hidden treasure here.
Also, one can see what is on the screen from the last use until you
clear the screen after
powering it on, so if he has not done that, you will have an interesting
thing to get from
that.
I wonder where a mouse and 5 1/4 drive attached to this as he says?
that sounds
way later than Hazeltine survived by my memory to be correct. At least
I don't
think even the Alto's were out before Hazeltine had ceased to make this
style
terminal.
BTW the Hazeltine I recall with core dated from probably 68 or 69, if
this is
later it may have some other display memory.

Yes, but this is not a Hazeltine 2000. Its too modern for that. Plus
the Hazeltine 2000 has a different enclosure and says in huge letters
"Hazeltine 2000" on the front. So this is something different. I
asked him to post a detail photo fo the connectors on the bottom left.
Its always possible that Hazeltine did make some sort of weird
computer. I just never heard of one and searching all the usual
suspects (1000bit.net, old-computers.com, etc.) didn't turn up any
computers under the Hazeltine brand.

I've got a Hazeltine 5.25" 96tpi DSDD CP/M diskette in my sample
collection, so yes, they did make a computer. Probably along the
lines of many other terminal manufacturers--added a Z80 and diskette
controller to an existing terminal chassis.
I think I see 3 connectors, not two. At any rate, this looks to be a
notch up from the dreadful 1400 terminal that used tilde as a control
character (!).

Yes it depends also on what you want to call a
computer. Most of us want to pump diskettes into it
and whatnot, but I opened up an IBM terminal some
years ago and found alot of the guts of a typical
peecee. No, it probably didn't have any provision for
connecting anything but the k/b and display, but it
just goes to show how definitions can be open to
interpretation.
I'd like to get my hands on one of those. Thought it
might be fun to see what it would take to make a full
fledged pc out of it. A new chip there...solder a few
jumpers there...;). And the thing was capable of
analog color IIRC. I don't recall their being an
intensity input.

Does the term "thin client" sound familiar? :)
Even when a manufacturer had a terminal, some didn't bother with the
additional CPU and just used the same one used to run the display.
Before I had diskette drives, I ran an old Beehive editing terminal
with both a printer and a dual cassette (paper-tape substitute kind)
deck. I could do word processing of a sort on it; was it a computer?
Seems so to me. It had an 8008 CPU and shift-register memory. I
coiuldn't print with it, but that was my shortcoming--I didn't have
the proper printer for it--it had a printer port and a "print" key.

They say the microprocessor was invented to make terminals
inexpensive. For my purposes, terminal applies to anything designed
to act as such. Most have microprocessors with RAM and ROM, which
makes up a basic computer system. But they aren't designed to be used
as end-user computers, they're designed to talk serial I/O to some
remote computer if they're a terminal. That's why a regular PC with
terminal emulation software for the serial port doesn't count as a
terminal by my definition :-).
I'd like to get my hands on one of those. Thought

Just so everyone knows, I'm not interested in a Hazeltine computer, so
if anyone wants it they won't be bidding against me :-).

This is the monitor half of a Hazeltine Esprit terminal. I had
one on my desk for many years; it is hands-down the best terminal
that I have EVER used. I'd just about kill for one now, but I've not
been able to find one. Sadly, this one is useless because the
keyboard is missing.

Only if you don't have a keyboard :-). For instance, I just purchased
another Megatek Whizzard *base* sans keyboard and monitor so that I'd
have a spare for the Whizzard I purchased last year. To most people
it would be worthless because it doesn't have the keyboard (which is a
very interesting giant keyboard :-) or monitor, but to me its useful
as a source of spares.

I'm not sure if I'm ready to retreat from the "stick a CPU/floppy PCB
into a terminal" notion on this one yet. The seller seems to be
pretty sure that this was a computer, not just a terminal. If I have
time this weekend (doubtful, but I can dream), I'll dig out the
Hazeltine sample floppy and see what it says about what machine it
might have been associated with.
