In order to save space, most systems now use SIMMs or SIPs for their memory. These are small PC boards (about 3/4" by 4") with RAM chips (usually 8 or 9 surface mount) on them. SIMMs (Single in-line memory modules) have an edge connector (like on regular expansion cars) that plug into a special socket. SIPs (Single in-line pinned, sometimes spelled SIPPs) are SIMMS with pins soldered to the edge connector. These plug into sockets that look like one half of an IC socket. /mike -- \|/ Michael L.
