It was my understanding that ADB was only present on old-world Mac's (pre
G3 w/o USB) There are a few G3 stragglers which were old-world ROM systems
but those were not produced for very long and not many exist (namely the
7300 based, G3 Desktop) (see

I've heard several places that the old-world ROM was incomplete and bug
riddled. It's also stated here: http://penguinppc.org/bootloaders/quik/
Also see wikipedia:
http://en.wikipedia.org/wiki/Old_World_ROM
"
the Open Firmware implementation was just enough to enumerate PCI devices
and load the Toolbox ROM, and these Open Firmware revisions have several
bugs which must be worked around by boot loaders or nvramrc patches.

Given the infancy of the Haiku-PowerPC Port, focusing on more stable/newer
Power hardware may be beneficial.
The user base for ADB based apple systems is small;
the user base for ADB based systems with G3 upgrade cards is smaller;
the user base of users with ADB based systems, G3 upgrade cards that work
as generic CPU upgrades is smaller.;
