Take a look at:

They have both PCMCIA and PCI cards for digital IO. They also have USB
based products, but they will have propagation delays that may or may not be
acceptable for your application.

Subject: [PEDA] Testing Boards?
Could someone give a recommendation for a device that will allow me to add
ttl-style I/O to a PC or laptop?
Now that parallel ports have gone the way of serial ports, I can't
bit-bang a parallel port anymore.
I've done a poor-man's SPI port, JTAG programmer, and other tasks using
the parallel port, and would like to do some of this with my laptop sans
parallel port. Is there a logic analyzer or some other device out there
that could be plugged into a USB port to provide bit-bangable I/O?
