Stated Tothwolf tothw...@concentric.net:
"Both contact surfaces must also be the same material or tin oxide will form on the surface of the gold plating and cause a major headache. This was a serious problem with 486 and earlier Pentium PCs with 30 and 72 pin SIMMs and it led to a number of lawsuits." Almost every DEC System Unit ("backplane") that I've ever seen uses tinned-contacts, yet the Modules all use gold-plated fingers. How does that situation jibe with the SIMM issue/experience? ----- paul
