I had a Freedom 100 on my Morrow (CP/M) and never had any problems with it.
I don't know what their reputation is.  I know nothing about Wyse terminals.

>One more thing, anybody have any comments between amber and green screens?

This is a sensitive subject for me.  I was evaluating Qume VT102 terminals
a few years ago.  I got the termcap entry set up and working and had decided
that I liked the thing.  Then someone brought in the "newest ergonomic" model:
amber screen.  We were told that these were better than the green one I had
been using.

Well, within two hours my color vision was really screwed up and I had a
headache.  Looking at something black & white, I saw black & blue.  Everything
else looked funny too.  The headache came from the lack of contrast on this
particular monitor.

I haven't worked with an amber monitor since, at least not long enough to get
a headache.  But every time I try and read from one, my color vision starts
to go.

Some people swear by amber monitors.  I'd quit before I would work on one.  
In general it's probably just personal preference, but I would be a wreck if I 
had to stare at one of those things all day.

If you're going to be buying several, try and get a green evaluation unit in
as well as an amber one.  Have the intended users work for a day at each.
You may find that you buy a mixture of them.

Ergonomics is NOT a fixed set of rules: "do this."  Really it's listening to
the users of the equipment.  The only "rules" are rules of thumb that work
MOST of the time and point you away from inflexible, unadjustable, uncomfort-
able equipment.

Just my $0.02 worth.
