A friend of mine has gotten himself into such an embarassing fix, he wants me to post this query (remaining anonymous himself): The scenario: He installed SIMMs into his MacIIcx. For good reasons, he then wanted to remove them again. In doing so, he broke one of the retaining clips on one of the SIMM sockets, with the result that attempts at installing SIMMs in that socket again are unsuccessful - the SIMM will not click in place. What should this poor person do, or where can he find someone to fix this - or does it entail a full motherboard change? Best regards, Sigurd Meldal (My MacII still has its full complement of SIMMs - this actually is posted for somebody else.)

Broken SIMM sockets are quite common. I hope the manufacturers of these sockets act soon to correct the problem. For now, however, the best thing to do is avoid the problem altogether: I once worked in a lab where I had to debug a board with several different memory configurations. I had to remove and install SIMMs about every 20 minutes. I found that it is fairly easy to _install_ the SIMM, but very difficult to _remove_ it. If you push outward with your thumbs or forefinger gently on the pieces that hold the SIMM vertical, and at the same time ease the SIMM forward, you'll find the job alot easier. More pressure should be used outward on the vertical pieces than on the SIMM itself. I hope this saves someone from future hastles!

OK, I'll admit it, I have a broken SIMM socket after upgrading to 4 megs. So far my Mac+ seems to be working with the SIMM held down only at one end. However, I would like to replace the defective socket. Someone had posted that SIMM sockets could be purchased from Digi-Key (Or something like that) and indicated that before I call I should have the measurements. I have a catalog from the company, and indeed there are several variations of SIMM sockets. My question is: Does anyone know the part number of the socket I should order for the Mac+?
