Recently my sister called to tell me that her mac 512KE wasn't accepting any disks of hers. She tried the external drive on another machine and it worked as did the disks. All this lead me to suspect a hardware problem. I checked AppleLink's service database and found that there are 2 things to do at this point--one is to replace a chip in position d8, the disk controller apparently and if that doesn't work, to swap the logic board. I was hoping to attempt a repair with my partner who is fairly expert at reparing IBM PC's and clones. I would like to know if we will be able to do this easily --can we swap out the chip in d8 from the mac plus or SE or do we need a 512KE specifically? Is the chip identified on the board or do we need some sort of documntation which we don't have? Can we avoid the shocker on the video board or will this be a dangerous sort of undertaking ? Can the case be opened with just the torx screwdriver and some perseverance and ingenuity? Are their other considerations here (warranty aside, since there is none anymore). Thanks in advance for the technical support. __ DC P.S. The symptoms which I neglected to list above are the way the disks are ejected and the disk-with-an-x-in-it is displayed in both drives. Thanks again. -- David Cohen {uunet}!mstan\ Big Electric Cat Public Unix {bellcore,cmcl2}!cucard!dasys1!cohen New York, NY, USA {sun}!hoptoad/

Keep in mind, is could also be a disk drive problem. I had a similar problem and the drive was replaced and it is a happy mac now. -Andy Just say Wafna! Andy J.
