Hi all,
I've been looking into adding an LCD display to my TS-7400. I have
here a 2x20 HD44780-compatible with backlight.
(For background, I'm a software designer and budding electronics
hobbyist).
Of course, the TS-7400 does not have an LCD header or a parallel
port out. Is anyone aware of an LCDProc driver which could be used
to drive the display via some of the GPIO pins (4-bit is fine for my
purposes, for now) or the GPBUS, or such? It almost seems like
it should just about be as easy as hacking an existing driver to
address the 7400's pin addresses instead of the parallel port
addresses, but I rather doubt that's the case.
My other thought was to build a simple serial-to-lcd daughterboard
using a shift register, as shown on the following pages:

Given my inexperience, this seems the easiest solution.
So: why am I wrong, where should I look for more information, and
what hideously simple solution am I overlooking?
Thanks in advance for any thoughts,
Torben
