Not-so-old laptops used to have parport connectors for a while, and can be found at a very cheap price or even for free by now with dead batteries. I've been using mine as a JTAG connector exclusively until I replaced this laptop. A number of old mini-itx boards used to have a parallell port and were easy to hack on (eg: those with a jack power connector, onboard video and a PXE capable NIC to boot the freshly built kernel over the network). They're less easy to find though. If you want to run on your PC, you'll have to order a PCIe parallel port NIC I guess.
