Sounds like it could also be an analog board problem. Try here: http://home.earthlink.net/~gamba2/schematics.html Mac Plus, analog board schematic and Tech Notes (PDF, 104KB)
Also I think that code may indicate a memory error. Try re-seating your RAM. A place to start anyway... Good luck. Quoting "Brian Smallshaw" <[email protected]>: > Hello Group.
