Is it possible to convert a SIPP to a SIMM by cutting or unsoldering those little wire legs? If not, why not? ---- Anything you read here is my opinion and in no way represents Sybase, Inc. Jon Forrest WB6EDM

Get the data sheets on the parts and compare them. If the voltages are the same and the pins have the same function, you could probably do it fine. I've seen a couple motherboards with BOTH SIP and SIM sockets. It's likely that the voltages and functions of the chips are very close. The hardest part is going to be mounting the chips securely and modifying the wiring - without putting too long a wire on them, or frying the thing with your soldering iron. Have fun (but experiment on a cheap chip first!) -Rich -- * Rich Snow AOA-----------------* * (617)864-0201 * rich@aoa.utc.com Disclaimer: Lack of Disclaimer. * aoa!rich@bbn.com

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. That is, unless they're made by Intel :-) >The hardest part is going to be mounting the chips securely >and modifying the wiring - without putting too long a wire on them, or >frying the thing with your soldering iron. 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 media is in the business of distorting people's perception of reality, by emphasising the out of the ordinary.

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
