The Ambassador actually does require some padding at 19200 baud,
even a little at 9600.  However, it uses Xon/Xoff, so unless you
are running EMACS without flow control you'll never notice it;
since it requires similar padding to the HP 2621 (e.g. almost none).

Yes, it takes forever to redraw the 60 line screen.  Not because the
terminal is slow, but because it takes a long time to transmit 60
lines worth of text from a serial port.  The only padding needed on
this operation is 156ms on the clear screen sequence.  It would take
as long on any other 60 line terminal.

The Ambassador comes in landscape mode by default.  If you want to run
it with 60 lines, you should order it in portrait mode.

The Guru has a number of different screen sizes, including the default
33x80, 44x80, 76x89, 76x134, and 76x178.  Yes, that's right, you can get
a 76x178 table all on the screen at once.  The print is so tiny you'll
go blind trying to read it, but it's great for looking at the overall
shape of things.  The Guru is only available in landscape mode, last time
I checked, so you probably don't want to use it with more than about 44
lines for everyday use.

The Guru and the Ambassador also have green phosphor, although different
from the Blit.  The Ambassador has a slow phosphor, resulting in noticable
ghosting.  (I run mine in reverse video and the problem goes away.)  The
Guru has a faster phosphor, it's easy to look at in regular video, but it
flickers in reverse video mode.

You can get an Ambassador with white phosphor, it's called a Genie and
the major difference is that it won't put more than 30 lines on the screen.
It also costs less and is missing a few features.
