If the voltages If you think of the vendors as lazy, which they are, you would guess the pinouts etc would be exactly the same and the differences purely mechanical.

It's easy to go SIPP to SIMM. Just mount the SIPP in a vise, heat the pin with a soldering iron and use a needle nose to pull it off. (this assumes basic soldering iron capabilities on your part) Are you thinking of SIMM to SIPP? The local "cheap do it your self" computer store sells both simms and sipps. He charges $2.00 more for the sipps because he buys simms and the legs and solders the legs on. bruce -- Bruce O'Neel oneel@heasfs.gsfc.nasa.gov NASA/GSFC/STX/Code 664
