I'm in the very early stages of a potential project:  I have some 
software that uses LPT1 and LPT2 as general purpose IO to control 
various external widgets.  What I want to do is create a PCI card that 
looks like a couple parallel ports to the PC.  Then, rather than 
exposing simple high/low signals to the outside world, a PIC with CAN 
abilities will sit on the PCI card and translate the signals to the 
parallel ports to various CAN messages.  Those messages will then 
control the external widgets rather than the simple high/low signals.

So... my question to the list: does anyone have any design notes or 
schematics on PCI card based parallel ports?  I realize the parallel 
port is somewhat old-tech, but it is already well integrated into the PC 
software which is fairly specialized.

Any info is appreciated!!

Thanks,
Stan
