I just fixed a Mac SE which was displaying the following symptom: Turn on the Mac... and you get a Sad Mac with a low-numbered hex number The total repair cost was quoted to be over $150 by several different people, when the person having this problem came to me. The solution was to remove the main logic board,... remove all of the RAM memory (in SIMMs) and erase the edge connectors using a high quality eraser. Then replace the SIMMs. The Mac now works fine. If you experience a similar problem, you may wish to attempt this before spending 'lots of money' (college students don't have this) (The opinions herein are my own (sometimes). Warrenty may not be valid after this operation (but it should be). Have fun.)

Then replace the SIMMs. Hah! This is great! I remember my old TRS-80 (Radio Shack) Model 1. This was the fix for a poorly-working computer. The reason? The fools were too cheap to gold plate the edge connector contacts to keep gunk from forming on them. I don't mind saying that it is NOT reassuring to see this "Money-saving" practice coming back into vogue. I hope it was some third-party memory provider and not Apple, so we can easily avoid a brand or company name. > Matthew Kaufman > matthew@ucsck.ucsc.edu, matthew@ucscb.ucsc.edu, ...!ucbvax!ucscc!ucsck!matthew > (flames are unnecessary,... direct via e-mail if required) --chris
