Crosstalk XVI version 3.61 (and later, I suppose) and Mirror II provide work-
able VT100 (and most of VT102 in Mirror) emulations.  The default key mappings 
are not the best choices for all UNIX systems (both use Escape as the program's
attention key, and vi and emacs both use Escape - the attention key is
mappable and I use PgDn).

I haven't tried Crosstalk Mark IV or Mirror III (which are competing products
at the next level up from Crosstalk XVI).

Both programs work with the #2 SCCS OSS, which uses split screen, partial
screen scroll, and partial screen reverse scroll.  I consider this application
a better test of VT100 compatibility than either vi or emacs (after 5 years of
trying different VT100 'compatible' terminals and programs for users in 5
states).

Crosstalk handles the color extensions of the X3.64 standard (haven't tried
them with Mirror yet, but expect that it does also).  Color terminals are
used on a number of AT&T products (computers and switching machines) and there
are a limited number of suppliers who produce X3.64 color terminals, either as
their own product, or as an OEM (Data Media in New Jersey).
