Does anyone know what a Macintosh 512K Sad-Mac error code of 0000DB indicates? I believe this would be a class-code of 00, but I cant find any documentation online about this type of error. I am debugging a processor emulator in the 68000 socket, so I am sure that the motherboard is good.
Its a new project. I agree that my emulator is doing something wrong or there is a signal integrity issue. I was hoping to use the error code to help isolate the error, or to understand why the Mac is unhappy, but I have not ben able to find out what class-code 00 is for. Or maybe my emulator is just not updating the register properly with the correct class-code that the Mac is trying to write.
