A co-worker did the slot-1 modification (where you have to drill a hole). It works, but he's had problems with wires breaking (he had to solder a wire near the edge connector pins, and that wire is constantly breaking off -- the top of the motherboard socket can hit the wire and knock it loose). I did the socket-370-to-slot-1 modification, and it's easier -- no drilling, and just one wire to solder. I don't have any problems with breaking wires. However, the adapters I have use tin plated edge connectors, and so I may have oxidation problems later on; it works, though, and I'll look to replace them with gold-plated adapters someday. The soldering was tricky, though, due to the small wire and pads. You'll need a very fine-tipped soldering iron, at least, and a stereo microscope or magnifier (one of those circular fluorescent lamps with a huge magnifier in the middle) will make things much easier. You'll need very good eyes, otherwise. -- Darryl Okahata darrylo@sr.hp.com DISCLAIMER: this message is the author's personal opinion and does not constitute the support, opinion, or policy of Hewlett-Packard, or of the little green men that have been following him all day.
