I've now included the schematic, PCB layout and artwork laser printer .prn file for my JTAG interface in file jtag.zip. Just copy jtag.prn to the laser printer to produce a transparency for making the PCB. Tracing paper works very well. Red tracks are wire links on top of the board. I used a 74HC244 instead of a 74AC244, as I've got lots of them. With a short cable length like I'm using (about 12 cm) it doesn't really matter. Leon
