Well I did suggest that he put a triple row of holes down the edge to fit a DIN 41419 style connector, and for those not using these you can fit pin header strips up to 64 pins long, so with a double row you could have 128 pins. My suggestion was for the PCB to be Eurocard size, but haven't seen any comment on this. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
