The video pattern is usually caused by failing capacitors on the logic board. Your old hard drive is probably dead, but it might be just "stiction." While the question mark is showing, go ahead and slap the side of the Mac -- you might get lucky. >If I put the OS 6 install disk in, it changes to smiley-face for a >second then reverts to disk & X. The Mac starts to read the floppy, then encounters an error. Either the floppy drive is dirty or the floppy disk is bad. >If I put the OS 7.1 Install disk in, it begins to start up then freezes >about half-way through the startup. Same, just gets a bit further along. Check the FAQ for instructions on cleaning the floppy drive, or just get a floppy cleaning kit from your local computer store. >So, how about some general hints as to how to approach the >resuscitation? I have a couple of hard drives (an 8o mb and a 500Mb >which I rescued from the dead IIFX). Floppy drives are easy to clean, and hard drives are easy to replace (if you have a torx tool to open the case). The video pattern is a difficult problem. Sometimes reseating the ROM SIMM helps, or cleaning around the capacitors with rubbing alcohol (the ROM SIMM is by itself, apart from the 8 RAM SIMMs). Do not try to replace the capacitors without the proper tools. Finally, once you get it going, it will probably not remember the date, time, and other settings. To fix this you need a new PRAM battery. Bryan Kattwinkel <mailto:[EMAIL PROTECTED]> -- Compact Macs is sponsored by <http://lowendmac.com/> and...
