SIMMS stands for Single In-line Memory Modules. They are tiny circuit boards with chips eight chips on them (9 for IBM's or computers that need a parity chip). This is what they look like: (sort of :) _________________________________ / ___ ___ ___ ___ ___ ___ ___ ___ | || | | | | | | | || || | | | | | | | || ||___|___|___|___|___|___|___|___|| -|||||||||||||||||||||||||||||||||- Each one of those eight squares is a chip. The bottom part is similar to the bottom prongs on an expansion card, except much smaller. These SIMMS come in either 256k or 1Mb. A memory card (or a motherboard on some computers) that accept SIMMS wil usually four to eight 'slots' that you plug these simes into. The chips on the SIMMS are soldered on and can't be taken off 1 by one as with 256k x 8 chips. Hope this helps. ____________________________________________________________________ | | | | This is your brain... | BITNET-- mquinn@utcvm | | This is your brain on drugs... | pro-line: | | This is your brain on whole wheat.| mquinn@pro-gsplus.cts.com | |____________________________________|_______________________________|
