If the Sad Mac shows up in the middle of running an application the codes don't mean diddly squat. A wild jump into the ROM could get you anywhere, with anything happening. Those error codes only have meaning when displayed at Reset time, since only then is the proper software in control of the error display routine. In other words, you don't know any more than you did when you started! (Namely it's broke.) +----------------+ ! II CCCCCC ! Jim Cathey ! II SSSSCC ! ISC Systems Corp. ! II CC !
