Well, it has an 8080 microprocessor, ROM, RAM, input (keyboard and
serial), and output (video display and serial). What more do you want? :-)
4:32 p.m.
What I like even more is thatit's nothing more than a plain generic dust cover -
retail cost about $2and notice the generic product tag with the "hand written"
note saying "DEC VT100".
Wow, can I stick a hand written sticker on an old 13" CRT claiming its a DEC terminal
and sell it for lots of money?/sarcasm

I'd assumed it was a dust cover shaped to fit fairly closely on a VT100
terminal. Such things (for all sorts of desktop computers, terminals,
printers, etc) were not uncommon at ome time, but are not easy to get now.
If it is that, I can understand why somebody might want it in their
collection.

The VT100/VT125?? that I gave away last year had one made by DEC, and a
DEC tilt/swivel base. Now I feel bad about losing the DEC VT100 keyboard
dust cover.
It had some damage; I had to retrieve it after the college dumpstered MY
collection (in spite of specific paperwork from the dean authorizing it!)
I'd like to drop it on a college administrator's head.

Yeah, its just a dust cover, but some models of VT100 are bona-fide
computers.
There is one with a PDP-8 (called a DECmate) and one with an LSI-11
(called a VT180).

Thanks for the correction; that was from memory. I think I have one

The VT180 is a CP/M machine (IIRC). The VT103 has the LSI-11 backplane.

Chuck and I each used to get a lot of disks to convert where the owner was
unable to even say what machine they came from.
"My computer is clearly labelled. It is a:
Lear Sigler
VT100
ADM-3A
Wyse
Televideo
"
But are they looking at the computer, or at a terminal? A lot of those
had Morrow Designs, Northstar, etc. copyright messages in the system
tracks of the disk.
Out in my storage shed, I have a "DISKON" computer, which is a single
board computer that was built into a slightly modified Televideo terminal.
They were peddled for disk format conversion. At one point, I offered it
here and didn't get any takers. When I tried to boot it, I got a disk
read error.

There there is the VT100 look alike the VT180 which uses all the VT100
boards
and an additional VT180 board (Z80, 64K ram, FDC, serial ports..). Many
of the
upgraded Vt100s that ran CP/M still have the VT100 badge.
There there wer the VT103s, a vt100 with a Qbus card rack and could have
and of the Qbus PDP11s (and i've even seen Qbus microVAX) board in them!
Vt100 was the first DEC terminal that wasn't a state machine or some random
logic sortacpu. However there were a lot of 8080based Terminals before the
8085, z80 and cheaper 8048 hit the scene.

state machine or some random
The distinmction between a 'state machine' and a 'processor' is somwhat
blurred, IMHO. Personally, I consider the VT50-series controller to be a
simple processor, I guess you call it a state machine.
I could even argue that the distinctiuon can come down to how it was
designed, a 'state machine' is desiged from a state transition diagram, a
'procesosr' runs a program which is descibed by a listing. The
VT50=-series was certainly the latter (there's a source listing of the
fimrware in one of the microfiches).

You forgot "Hazeltime". I was looking through my archive and spotted
a disk labeled that. I recall, unsuccessfully, trying to get the
owner of the system to tell me what it *really* was. He didn't send
me a system disk, so I never did find out...

P.S. I hated the Hazeltine 1400. Who the heck uses tilde as an
escape lead-in character?

From what I can see, that;' a dust cover, and it
would fit various
computers that were in the same case as the VT100 (the VT103 and
the
VT180 spring to mind.
Anyway, there's an 8080 in the VT100, so it's a dedciated computer, I
guess :-)
