Unfortunately that is simple the WRONG size. The hp uses 2mm or .079 inch spacing just to confuse people. Joel Kolsted did manage to find some of the proper size connectors for Fujitsu. BUT as he stressed, and I didn't believe till I got a few from him, they are worthless. They are so increadibly small and flimsy that they are not worth a damn thing. I would encourage anyone looking for them to keep after Dupont and try to get the double row 4 pin 2mm connectors. That is 4 pins top and bottom. They don't fall apart when you try to stick the pins into them (like the Fujitsu) because you don't have to stick the pins in. You just solder the wires on. I have built many many cables from a couple double row 25 pin wide connectors that someone gave me that I hacked up into sections of 4 each. So, ignore anything regarding .1 inch connectors. If you can get them on they will have damaged your calculator. ian -- -=Runaway Daemon=-
