Probably all that's wrong with it is a blown fuse. (that happened to a TRS-80 Model I P/S that I had). To get it open, take a utility knife (the kind with snap-off blades) with a new blade, and a blow torch. Use the blow torch to heat the knife, then "cut" around the P/S until the top half pops off the bottom half. I use this method to open old laptop batteries to replace the cells. When you get the P/S fixed, just put the two halves back together, (sand [or cut] the ridges off made by the hot knife, first) and put a bead of hot glue in the seam to hold it together. It doesn't look that bad, and It can always be popped apart with a screwdriver if you need to fix it again. GooD LucK, ---------- <classiccmp(a)u.washington.edu> anyone I've
