Looking for advice on using stamp to emulate key presses

Posts: 46,084
I'm about to embark on a project to put a PC in my van. The primary function
is to play mp3s, but i would also like to incorporate some basic dos
programs to rip CDs (ones I've bought, of course!) and possibly other
functions. I already have a Javelin stamp and an LCD screen in the van, and
would like to interface this with the pc. any suggestions?
The software I'm planning to run to play mp3's repsonds to single key
presses - how can I use the stamp to mimic a keyboard? I plan on having the
pc always on, with an interface between the stamp and the keyboard port on
the pc, so the stamp sends the key presses that a keyboard would.
Also, I would like to interface the LCD to both the stamp and the PC -
either by routing the output of the PCs parallel port through the stamp, or
possibly by having dual inputs on each of the LCD pins. anyone done this?
I'm just starting on this, I'm sure I'll have lots to work out. Thanks for
the help!

under AlDemo\PC_Keyboard_Replace.txt, is
a copy of the earlier group message, with
spaces properly inserted (I hope).
This demo shows what wires to connect, and
how to send the data, to convince the PC it's
got a keyboard, when it's really the BS2
sending the data.
If you can do it with keypresses, this demo
shows how to get them into the PC.
Note the PC to keyboard cable was 'supposed'
to be less than 10 feet -- so the BS2
keyboard replacement will need to be close
to the PC.
