<< The empty ROM slots on Macs were intended to be used to support ROM updates. Apple never shipped one, so the slots stand empty.

Early production usually uses mask-programmed ROMs, also in a ROM SIMM. General availability production uses soldered, mask-programmed ROMs, usually identical to the early production ROMs. Late production often leaves out the ROM SIMM socket entirely. If your machine doesn't use a ROM SIMM, there's no reason to muck with the ROM SIMM socket at all. [ * ] Most notable: any "six slot" PCI Mac.
