I and a couple of other people thought it would
be fun to build
our own stand alone video terminal. The prototype is a 3x5" PCB
that is completely self contained - all you need to connect is a
VGA monitor, a PS/2 keyboard, 12V power, and a RS-232 connection to
a host computer of your choice. The idea is that you could easily
stick one inside the case of an old VGA monitor,
add a keyboard, and then have an ASCII terminal. No PC required
:-)
Hmm, I don't suppose NTSC TV is good enough to offer 80x25 text on a
TV set, is it? That'd be rather useful as a way of sneaking a
terminal into the lounge :-)
Probably not, but now that most people will probably have some sort of
HDTV in their living room, you could always output 480P or 720P video
to it through a Y/Pb/Pr "component" or HDMI-compatible output. I'm
guessing that doing that will complicate the video display, though.
Enough
firmware finished now to be a functional VT220 clone
Including vomit-inducing smooth scroll? :-)
Hey, I like smooth scroll, my only complaint is that it's so slow. :)
