Macintosh 512K error class code 00

[MicroCoreLabs]

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.

I would say that the processor emulator has a problem, or is causing a problem with the mac. If the mac works fine with a normal 68000 installed, it's something the emulator is doing.

I'd hazard a guess something like memory corruption, incorrect timings or not processing instructions correctly.

Are you trying a PiStorm in it or something?

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.
