I'd like those goodies as I will be needing something of this nature in
the future for Falcon 4.0 and my pit.

Ok folks.I've uploaded (circuit.jpg) the circuit diagram for the 5451
LED driver to the ftp site.  In a single chip configuration, the chip
connects to pins 2,3 and 18 of the parallel printer port.  As always,
please be careful in working with ports on your PC.  If anyone needs
help with the code portion, I can only help if you're interested in VB.
Also, my code requires the use of a 3rd party driver called VBIO (it's
free, and I believe I have a copy somewhere as well).  When I last
played with the code, I was running a Win98SE PC, so I haven't tested on
any other OS.
