Browse around on hackaday, a DIY tech project website and feature blog mostly for hardware hacks and projects.
I think you could probably hack something together with a $1/free shipping USB Digispark (ATmicro85)to control everything some soldered on leads with alligator clips to grip some sewing needles as well as some sort of jig to hold the needles against the correct pins. Get the Arduino IDE and you should have an easy and cheap time with the JTAG hardware the only real difficulty is jigging the pin connections.

I use the Arduino IDE for all sorts of fast dirty Atmel controller based automation and communication hacks, the hardware and the available libs and ease of use cant be beat even if you are not a great programmer.
