Please note that this image depicts a SIMM and not a SIPP as per the title. --Ali@gwc.org.uk 18:53, 9 January 2006 (UTC)[reply]

Sorry, but you are mistaken. Why do you believe it is not SIPP? --Anthony Ivanoff 05:58, 10 January 2006 (UTC)[reply]

because a SIPP looks like this [1] i.e. it has pins instead of contact pads --Ali@gwc.org.uk 17:52, 10 January 2006 (UTC)[reply]

That's right. Now look carefully at my picture. I pulled these modules out of a 286 box. There were two memory units that had pins, and that was how they were plugged into the motherboard. In this picture, you can see the pins on the bottom of the rightmost memory module, and the other module stands on these pins. Each of these modules consist of two boards with microchips. One of these boards is shown on the foreground. I've taken another picture for clarification: [2] --Anthony Ivanoff 19:20, 10 January 2006 (UTC)[reply]

A memory module (SIPP, SIMM or DIMM) is a single circuit board with a number of chips mounted on it. A SIPP has pins soldered directly to this circuit board; these pins slot into matching spring-loaded holes on the motherboard. A SIMM has plated pads which make contact with spring loaded contacts in a plastic socket. What your new picture depicts looks to me like a SIMM in a double SIMM socket which has been de-soldered from a motherboard. It doesn't matter that it came from a 286; not all 286s used SIPPs. The item in the lower foreground of the image in this article is a 30-pin SIMM. If you don't believe me try doing a google images search for "SIPP" and for "30 pin SIMM". --Ali@gwc.org.uk 19:53, 10 January 2006 (UTC)[reply]

I'm in doubt. You may be right. I'm calling for other people's opinions at WP:3O. --Anthony Ivanoff 20:12, 10 January 2006 (UTC) BTW, it was not soldered out but just unplugged from motherboard.[reply]

In that case the plastic parts must be some kind of SIMM -> SIPP adaptor. Similar devices (albeit with some active components) existed during the transition from 30-pin to 72-pin SIMMs. --Ali@gwc.org.uk 20:48, 10 January 2006 (UTC)[reply]

guys... theres a number on the chip... ever heard of google? here ill do it for you...... and ill point to you its specsheet [3] where it clearly says "pins 20" and thats from searching mcm514256az10 the part number (which ive now memorized) so it is obviously sipp as simm doesnt have pins and this part number does... perhaps the pins were broken or something or perhaps they are really short pins either way, this photo must be of sipp but it has 30 pin slots... so ... wow, im actually quite confused as to what the hell you have there S3raph1m 03:26, 17 January 2006 (UTC)[reply]

That part number refers to the actual memory chips which do have twenty pins. Two of those chips are mounted on the circuit board and the complete assembly is a SIMM. --Ali@gwc.org.uk 08:34, 17 January 2006 (UTC)[reply]

i never thought of that... well without pins on those pcb's it would be simm, but the second picture... it has pins... so im not sure, but the item in this picture is NOT sipp

the device shown in the second picture is one of these simm -> sipp adaptor. That is why you see the pins on it. --Ali@gwc.org.uk 19:40, 17 January 2006 (UTC)[reply]

Got here from WP:3O — definitely a SIMM. I would recommend changing the name to SIMMtoSIPP_adapter.jpg, but you can hardly see the thing! Can you take another picture, at an angle showing the bottom of the adapter? Cheers! (I've delisted this page at 3O.) --Mgreenbe 00:43, 9 February 2006 (UTC)[reply]
