For general use...a Wyse 60. Why?
It only cost me a few dollars.
It's *light*, so I can drag it around everywhere.
It's highly configurable - on-screen programming.
It has a printer port to dump the screen to hardcopy.
Cheers,
Aaron

A Decwriter III. It allows one to keep a log of console messages that
don't go away when a system crashes.
As to terminals with CRTs, the HP2382A is nice and compact, the text
is clear and easy on the eyes. It needs frequent cleaning due to the
fan sucking in dust, however, and the keys stick at times. If it gets
too dusty, it stops working (the text on the screen becomes tiny and
then won't appear at all). No VT-100 emulation, alas, but works great
with UNIX systems.

Hi,
For general use...a Wyse 60. Why?
Errm....were you aware of the fact that Wyse 30's and 60's have been
"banned"
in Europe due to the amount of X radiation they put out?
We had to scrap about 50 of the things a few years ago at a place I worked
because of this.... :-(
Use with caution; personally I won't use my Wyse 30s anymore because of this.

15kV on the final anode and a normal sort of beam current.
Quite simply, under those conditions you will not get hard X-rays.
I realize that Tony didn't post the original, but if you want a Wyse60 with
a _really dim_ CRT let me know :-).
But for Tony and others, the radiation component for monitors measures:
magnetic fields
visible light bands
ultra-violet thru x-ray bands
Part of the equation comes from the circuitry and the accellerating
potential on the electrons, and part is the phosphor composition (which
converts the kinetic energy of electrons into other wavelengths of course).
I've got a handbook on this somewhere but I think it is also on-line on the
US FCC site or the Dept of Commerce.

I've been particularly amused by recent advertisements for "radiation-free"
monitors. What the hell use would that be? (Except perhaps as a paper
weight.)

Hi Tony,
Rubbish!. Not that they've been banned, but that
they give out
significant amounts of X-rays.
Well, both the college and factory I've worked at over the last three years
had received communications from Health and Safety to the effect that these
terminals should not be used. That's why I said "banned" rather than
banned,
IYSWIM?
I would love to know what measurements were actually
made, and under
what conditions....
Me too, I never saw the original "memo". All I was told was that the terminals
were being taken out of service and broken up - they wouldn't let me rescue
them either. :-(
Annoying as I've always wanted a 60.
Well, check the final anode voltage (with an EHT
meter). Check the beam
current (if you can). And only then start worrying.
I don't have an EHT probe for either my meter or 'scope, perhaps it's time I
got one....
TTFN - Pete.

I hate to say "best," but I really like my WYSE WY-99GT... will do VT-100
and VT-52 and ANSI... I think it does a few others but I'm not sure. It
has "WYSE Works" built in-- Function-CAPS I think. It has a calandar,
calculator, and character map. Setup is very easy (full screen menus)...
and I really like the keyboard!

Without a doubt, a DEC VT420 that accepts two inputs! They look nice, have
good screens, a nice keyboard, and the dual inputs let you use it for two
computers, or two different connections to the same system. You can also
attach something like a DEC LA75 printer to on of the inputs and get
printouts! The VT420/LA75 combo is perfect, and I use it on my PDP-11/73.
I've got another pair that will probably end up on either my MicroVAX 3 or
PDP-11/44. I also use 420's on Sparc's and Alpha's.

I don't know how good they really were, but the marketing & sales people
at Telebit found some itty bitty CRT terminals they used at trade shows.
IIRC the screen had maybe a nine inch diagonal.
I think they were made by ITT; I don't recall seeing a "Qume" logo on them,
but . The small size made them ideal for situations where space was
at a premium.
I wish I knew more about them, and especially where to find them.

Hi Mike,
Anybody have a favorite? Why?
My favourites used to be the Televideo 950s which I got with my first
PDP-11/23 back in '89.
They were shaped rather like VT-100s, but not as wide. They had great
keyboards and due to their shape were easy to stack things on - including
other TV-950s.
Also got rather a soft spot for an earlier model of Televideo terminal which I
can't remember the model number of right now....shaped rather like the old
ADM-3A's. Great keyboard, and easy to service since they're well laid out
inside and the top cover is hinged at the back.
Current favourites are the DEC VT220 (and later) line - compact and very
versatile. And the HP terminals (I forget the model number) which are commonly
used on HP 3000 mainframes. Again they're stackable, and the ability to scroll
backwards to see earlier screen output is a godsend - I can't understand why
other manufacturers haven't included a similar feature on their units.
TTFN - Pete.

How do you enable VT-100 emulation with the TVI-950? Is this
possible?? I agree that the ability to stack things on top of one of
these is a good feature that's missing from a lot of terminals... ok,
it's got some tilt to it, but at least things like modems, books, etc.
and some other equiipment can be stacked on it as long as ventilation
isn't blocked off for too long when it's on.
I never quite understood the concept of computer equipment designed in
such a way that stacking things on top of it was difficult or
hazardous. Don't manufacturers realize that it's difficult to stack
things that aren't shaped for stacking, and that stackability is
helpful for saving space, which many of us are short on? The worst
offenders seem to be those new Macintoshes, in assorted
colors... those should win an award for the worst computer design of
the century; in order to make one of them useful, one would have to
build a wood frame, or somesuch, around one, which one should be able
to deduct from the purchase price.

Its because you're NOT supposed to stack stuff on top of the monitors.
Since people cant seem to grasp that simple concept, the manufacturers
have to slope the tops more and more. the heating vents on the top
should have given you a clue as to why they dont want books and papers
stored there...

the charges. One of the 4 edit sessions is almost always somewhere
in the cross-reference at the end of the listing which then allows me to
look at 3 of those references at the same time within the rest of the
listing.
I also find the other 4 terminals very useful during a DEBUG session
to display that portion of the listing which is being checked out.
The problem during a DEBUG session is that the terminal allows
only 24 lines at a time from the listing and once the program is
frozen within the DEBUG output, so are the rest of the terminals.
Having a total of 4 edit sessions with 4 different parts of the
listing really helps.
One of these years, I will connect another system up with TCP/IP
to allow a fast transfer so that I can use one PDP-11 within the
DEBUG session and the other 4 terminals on the other PDP-11
looking at the listing AND not frozen in place.

I always used different terminals on different computers. But just an idea,
why don't you get something with XWindows, so you could see all this
sessions on one screen ?

That's exactly what I'm working on. Given the large number of UN*X
machines I have (suns, vaxen, x86s..) I'm working on this setup: My
multiport serial card goes into my p166 Linux box. My SparcII displays
(over the ethernet) kermit sessions for each of the serial ports in a
different window (it has a 19" monitor on it that's actually quite nice to
read). A mass of serial cables goes from one side of the room to the
other...

Oh, VT52s (and similar), H19s, Most Newburys, some Beehives, etc all have

Incidentally, the IBM PC monitors (5151, 5153, 5154) all stack pretty
