http://www.mac.linux-m68k.org/status/MAC_MODEL_PB520.php states :
1. PMU ADB: Status unknown.
I suppose ADB is the apple desktop bus: does it mean that there is no
known way to use its native keyboard/mouse ? If so, is there any
alternative ?
May be working with recent kernels, please see this list or
linux-m68k@vger.kernel.org.
2. NCR5380 SCSI: Broken
Does that mean that it will not use scsi at all ? I'm not certain the
internal hard drive is scsi (it's not very clear to me from the specs).
The internal HD is IDE IIRC.
3. Serial: Broken. Cannot be used from userspace, but can be used for
kernel debugging.
My understanding is that I would not be able to use it to get TCP/IP
with a null-modem cable as I'm doing with the Macintosh SE right now.
Correct. The mac serial driver needs to be revived.
3. SONIC ethernet: OK.
Is that the internal AAUI ethernet controler ? That'd be great
because I found a working adapter to hook it on a regular ethernet
switch.
Should be it.
4.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.
I suppose i'm just too green to understand what it means yet, for now
the only peripheral I tried to plug was an Asanté micro en/sc (and
that's scsi), with no success but I didnt try very long thanks to the
AAUI ethernet adapter.
The Asante SCSI ethernet adapter does _not_ work. I banged my head
against that one for a brief period, then gave up.
