Sorry, I don't see the original of this misstatement
The first generation Nubus PowerMacs use essentially an unmodified 68K
ROM for booting, emulating a 68LC040 to do so. Also, Mac and Lisa firmware
are completely different from each other.
The second generation machines with PCI had Open Firmware.
"New World" refers to ROM in RAM systems which have pretty much just
some hardware init and OF in them and started around the time of the iMac
