Fresh from SMC, this programmable ROM SIMM replaces and improves multiple early Apple ROM SIMMs; preprogrammed with loads of goodies to get your mac up and running faster than before.

The new Crucible app is super convenient when you’re ready to customize your ROM SIMM. You can use either a generic PLCC32 compatible programmer, Doug’s SIMM programmer, or other options. When you’re ready to get flashy there’s also user-expandable space for an LED (wow!)

Busted ROM socket got you down? Check out my listing for ROM Clips.
