OK, remember I don't think I've ever tried PPC via MacOS booting, so
not familiar with it.
I will try to set up a MacOS guest in QEMU, to see if the hang can be
reproduced that way.
QEMU appears to be incompatible with the Old World ROM from the Beige G3.
'qemu-system-ppc -M g3beige -bios 78F57389.ROM -serial stdio' drops into a
ROM diagnostic menu and won't boot.
I did get 'qemu-system-ppc -M mac99 ...' to boot into MacOS 9, by using
OpenBIOS instead of Apple firmware. Unforunately, BootX is not compatible
with this configuration, so it won't help.
BootX is compatible with beige powermacs, but 'qemu-system-ppc -M g3beige'
with OpenBIOS fails to boot MacOS 9 ("MacOS: unable to find an interrupt
controller node").
OpenBIOS wouldn't boot a MacOS 8.1 CD-ROM either, but for different
reasons: both mac99 and g3beige failed with "No valid state has been set
by load or init-program".
