Guys, I got another iie with some problems.
There's no power going to the disk drives on my bad iie motherboard. The disk drive indicator light does not turn on and there's no spinning in the drive so it does not get any power from the motherboard. I have checked the power supply and it has power going into the motherboard. I have searched through several tech manuals but have no idea which chip controls the power going to the 5.25 disk controller.
I have been trying to find out through reading tech manuals which chip on the motherboard gives the power to the disk drives but I just can't find it.
Doing a pr#6 will hang the computer.
If I try a self test, the computer will self test forever, the only thing that changes is the amount of beeps.
I have tried removing and reinserting all the socketed chips on the motherboard, to no avail. I did however find a small amount of corrosion on the motherboard which I retouched with new solder.
The only thing I suppose I can do with it is use applesoft basic. When I turn on the motherboard, I get the apple //e and the command prompt.
