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
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.
