Supported for mice and keyboards. I am not sure how well other ADB devices work.
CD-ROM
Generally supported, but there are difficulties with certain models
CPU
G3 and G4 upgrades work, but you will need software to enable the L2 and/or L3 cache. Note that Umax S900 users have been reporting difficulties with the Sonnet G4/700 and G4/800 CPU upgrades in 10.2 and later.
The 603 and 604 processors work with Mac OS X 10.0 through 10.2 (i.e. not 10.3 or later).
The 601 processor does not work with Mac OS X.
Ethernet
Generally supported, but see notes on specific models below.
Floppy Drive
Not supported by Mac OS X.
Localtalk (that is, Appletalk over serial ports)
Not supported--unlikely to ever be supported
RAM
Supported :-) But it is worth noting that Mac OS X is pickier about RAM than Mac OS 9, so if you have marginal RAM, it may pass tests in Mac OS 9 and still cause problems in Mac OS X.
SCSI
Supported. However, Mac OS X is very picky about SCSI cables and termination issues.
Serial ports
Supported, but not for serial printers. It is possible that serial printer support could be added to the CUPS system.
Sound-in
Partly supported depending on model -- the mic input on the 7300 - 9600 is working now with version 3.1, but the RCA inputs on the 7600 etc. are not yet working.
Sound-out
Supported. Volume adjustment is working as of version 3.1.
Unsupported. I have not investigated these models--it might not be impossible.
6100, 7100, 8100
Unsupported, due to Nubus architecture and 601 CPU. Unlikely to be fixed.
5400, 5500, 6300, 6360, 6400, 6500
Unsupported, but in progress. The main problem is that SCSI and Ethernet are not working, which makes installation difficult. Also, will not work with Mac OS X 10.3 or later, because of 603 CPU.
Twentieth-Anniversay (TAM)
Unsupported, but work in progress.
7200
Unsupported, due to the 601 CPU. Unlikely to be fixed.
7300, 9500, 8600, 9600
Supported. See comments on specific features above.
7500
Supported. But requires CPU upgrade (i.e. does not work with original 601 CPU. And video in/out does not work.
7600, 8500
Supported. But video in/out does not work.
9500MP, 9600MP
Supported. But only one processor is active.
Beige G3's
Supported -- mainly for the sake of Panther (supported by Apple pre-Panther).
Early iMacs
Will be supported in XPF 4 (was supported by Apple pre-Tiger).
Supported. But built-in video does not work, so requires a video card.
PowerWave, PowerTower Pro
Supported. See comments on common features above.
Umax J700, S900
Supported. See comments on common features above. Also note that
Umax S900 users have been reporting difficulties with the Sonnet G4/700 and
G4/800 CPU upgrades in Mac OS X 10.2 and later.
