When the machine first powers on, the ROM is mapped to the zero address (0x00000000) to allow the Motorola 68040 processor to load the Stack Pointer (SP) and Program Counter (PC) for initial execution. The system then switches to the main ROM copy at , where the Mac OS toolbox and boot routines reside. This dual mapping strategy is key to understanding many of the hacks and optimizations that enthusiasts have developed over the years.

Even experienced techs mess up. Here is the trouble shooting matrix: : Unlike the Mac IIci, which often suffers

: It enables support for original hardware features such as SCSI disks, NuBus expansion slots, and built-in Ethernet (AAUI) within an emulated environment.

Do not attempt this with a cheap $10 programmer. You will end up with two expensive bricks.
