So I have a PowerMac 9600 that has a ROM slot, presumably if Apple ever wanted to update the 4MB Boot ROM for these machines and the other Old World Mac's that had the ROM Slot they just needed a ROM Upgrade SIMM.
It looks like the Beige G3 ROM SIMM is Pin compatible, so maybe someone that has designed PCB's could design a ROM SIMM PCB?
Elliot Nunn has created a tool that will decode the 4MB ROM image into its' parts where we can make edits/upgrades and it will also rebuild those ROM images.
Something that could be useful for Old World machines is we could upgrade the NanoKernel, upgrade Open Firmware, or replace Open Firmware with OpenBIOS of SLOF. We could upgrade the ATA manager or add 'ndrv's.
In real world use we could add support for booting from PCI cards like Firewire and USB and we could also add some words to the dictionary to add support for nVidia cards like the PCI GeForce 6200 ( Core Image on Old World Macs ). We could also add the Multi-boot boot picker found in New World Macs.
Also we could add support for the firmware to be able to read HFS/HFS+ disks from Open Firmware.
