Model: Performa 550

CUDA ADB: OK.

NCR5380 SCSI: Broken.

Serial: Broken. Cannot be used from userspace, but can be used for kernel debugging.

NuBus: If initialized by MacOS, some cards can cause an early kernel panic on some models. Workaround: boot MacOS with extensions off, or use Emile instead of Penguin.
