Parallel port logic analyzer

After reading the latest hackit post, [Ben] sent in this older, but simple logic analyzer. The software was written in windows, but the circuit is simple enough, and most hackers I know have more computers than immediate family members. The circuit uses a HC245 octal bus transceiver to feed the 8 data lines on the parallel port. (You can use a variety of chips for this application, most CMOS buffers will probably be fine.)
