Something like that, but with the target including close emulation of
VT100/VT220 (successfully runs emacs/vi/EDT, modernish setup menus,
etc.) A secondary goal is emulation of some common flavor of
graphical terminal ,Tek, etc. Emphasis on through-hole design, and
small form-factor.
One thing, to answer another question in this thread, is that will
only do 80-char-wide. The bandwidth of VGA over 640-pixels-wide
exceeds what the CPU and memory can do.

I don't
know where Z80s came into this. The VT-4 uses a 30ish-MIPS
microcontroller (to keep up with the demands of squirting out VGA
video). The video is essentially software-generated, keeping the
part count way down. Low part-count == low price.
Ah, I get confused a lot in these threads. Sort of something like
the ATMega8 TV terminal, except with a faster dot clock and more RAM?
