Roman,
Re LPT port, I was playing with the port and found I could get 8 outputs and
5 inputs.  I read that the 8 outputs could be used as inputs but read is
best not to do this for compatibility issues.  Does this sound true

Justin

I'll put the photos up on my web page soon, it
needs updating. The schematic is very simple, just
a switch to discnnect the MCLR/SCL/SDA lines, or
just the MCLR will work if you only have a one pole
switch. Then the rest of the box is a large
breadboard setup with leds, buttons, switches etc.

I always add a heap of wires with series resistors to
the PC parallel port via a simple cable and plug.
I can do bidirectional comms with many parallel
bits at quite high speeds. It always amuses me
that people try to implement serial protocols with
MAX chips and stuff. I gave up that years ago and
just connect everything to the PC parallel port,
it's just a couple of octal latches attached to
your pentium chip, and VERY high performance for
such a simple connection system.
