El JoPe Magnifico <firstname.lastname@example.org> wrote me that there are license differences
so the person who writes the Linux code just can't be the same person who
looks at the NetBSD code. Or some other similarly unintuitive workaround.
So is it easier to use the *bsd source or develop the drivers from scratch?
later on we could always replace code we don't like. :-)
(or what's the 'official' point of view about matters like these?)
I can only read (not too complex) C but I'd like to help, when necessary.

Oh, then I'll move the 80M disk to the Classic and put a 1G (or so) disk in the
Classic II so I can run macOS, Linux and maybe (open)bsd on it.

Oh, yes, I searched and remembered. The installation needs macOS to boot from.
Debian installation files go on the HFS partition.
BTW: does the floppy work in some *bsd flavour?

We could always patch the (installation) kernel so it thinks the display is
smaller, can't we?

Eh, sorry, I was writing from my own point of view. Of course the network works
(tcp/ip, etc), it's the hardware that needs to be supported.
I'll be using a plain Classic II which doesn't have any slots so I need the
external SCSI <-> Ethernet adapter which _surely_ isn't supported, yet.

I can test that here. Enough cables and machines (PC's, mainly).

Is there any difference (with regard to the serial ports) between the 2.1.x and

Just like mounting MSDOS (FATxx) filesystems on the PC? Cool!

I'm quite new to Macs so I don't know too much. ROMs shouldn't be used on PC's
but Mac ROMs can be 32-bit clean, I read. This means they can also be used

Argh! This is no good.

I run redhat on my PC and chose debian for my mac because they have these CD
images for FTP. Once we succeed in burning this image to CD-R I can try a few
I suppose this image is plain ISO9660 with rockridge extensions? Maybe some

I already wrote that once my Classic II can connect to an ethernet everything
is really OK: a truly portable linux box (and no plain laptop: i.e. a pc)!
I read that there are already some initiatives for supporting SCSI <-> Ethernet
adapters but I couldn't find out what adapters are being worked on, by whom or
what the status is. Does anybody have a clue about this?
