G3 Macs, iMacs, and others copy the ROM to protected RAM on boot.
Dumping an image to disk should be possible.

There is a utility called ROAM that copies the ROM to RAM and is
compatible with MacOS 9.04.

ROAM - Accelerate your ROM!
http://www.stg.com/employees/sbytnar/projects/rom_accelerator.html

"What is ROAM?

ROAM copies the ROM into RAM, and then causes the ROM memory to be
accessed from the RAM based copy instead of from the actual ROM DIMM.
This can possibly speed up PowerMacintoshes that do not already map
ROM into RAM."

Obviously, you would need another utility (MacsBug?) to dump the RAM image to disk.
