Mac SE High ROM image?

Hi everyone,

I'm attempting to restore a Mac SE (800K) with a bad high ROM.

Does anyone have a ROM BIN for a 342-0352-A?

I see Rob Braun has an image on his website but it's only 64KB and this is a 128KB ROM...

Thanks!

Eric

Yeah, it looks like my image is too small.
I don't have another one handy, but the ROMs are interleaved with each one making up 8 bits of every 16 bit word on the bus. If you've got an image usable in an emulator, you could de-interleave that and end up with burnable images.

I thought that might be the case, I was hoping for an easy solution :-)

I'll check around and see what kind of ROM image I can find...
