Old World Macintosh hardware used OpenFirmware [0] [1].

I had an older hand-me-down PowerMac and XServe that I fiddled with for a
short period of time ... OF is really quite cool.  But machines with
PowerPC CPUs weren't worth the hassle (less than perfect(?) hardware
support, comparatively slow, and not to mention the XServe was super loud!)
for me, so I got rid of them.

It is my understanding OF went away when Apple switched Macs to Intel
hardware.
