I've been doing a bit of research on m68k linux, macbsd (yuk!) and other *nixen that purportedly can/will run on the motorola 680x0 processor line.. The only two 680x0 based machines I have are a Macintosh Classic (68000) and a Macintosh Centris 610 (68LC040)
I can't seem to find a definitive answer on whether the Classic will run Linux - and I've heard a bunch of scary reports that state that the Centris with it's 68LC040 processor is a mad-house of problems and will probably never work without a wholesale processor replacement... (or will it?)
Can anyone offer any definitive answers on these two machines? I'd love to get the Classic running Linux... (my other alternatives for this machine include making it into a fish-bowl...

Forget Linux or any other Unix on the 68000. The 68000 lacks the MMU and virtual memory managemeent won't run without.

Depends on whether the LC040 behaves according to spec when it comes to F-line traps. Easy test: if it runs SoftwareFPU without crash, it will eventually run a Linux FPU emulator (there isn't any yet).
If it crashes, your LC040 is one of the many with a bug; Apple got slapped with a lawsuit for selling LC040 in machines that were advertised as 040. If yours is one of those, they should replace the LC040 with a 040 at no extra cost.

hi, according to the docs i got with my freeBSD rel. 2.1 cd-rom this *nix will not work with the classic and ALL 68LC040 macs. the classic has a 68000 only which lacks the memory management unit, which in turn is necessary to use virtual memory. virt. mem. seems to be essential for *nix machines. ok, the 68lc040 might work, but the keyboard and the mouse wonīt. formerly i used the lc475 which is very similar to the centris 610. for the lc475 they guys from freeBSD wrote this into some of the readme-files. on my quadra650, the freebsd runs nice. due to lack of time, i can only start the machine, enter some shell commands and say "shutdown now". that all works. i assignated approx. 300mb to freebsd on a scsi-disk-partition and that looks enough. sorry, more info i canīt provide due to limited time with freebsd. i bought it because i start collecting apple-related material.

How about the 475 (don`t know its marketing name..)? Anybody running Linux on it?
We`d like to use it for future replacement of MacOS if Raysody is there for PowerMACs;-).
Back to reality: Here many of these machines are used in 19" racks. An additional OS for different solutions (R&D) would be nice.

I think people are running Linux on the LC475 (or Performa 475) now, but you'll need a full 040, not a LC040 (no FPU emulator). And I guess keyboard support is still being worked on.

I have such a LC475 with a "full" 040 and booting with a ram-disk is possible (but no keyboard-support:-(. Is there a kernel already that supports ADB and SCSI for this machine?

No, not yet. Try booting vmlinux-991221.ELF, I've had one report that the keyboard worked with that one (and broke again with later kernels). Work on ADB has begun, I've not heard from someone working on the SCSI driver though I pointed several times in the right direction ...

Thanx, I can send you the 2nd report of a working keyboard on a 475. For SCSI, to which direction did you point? May we help you?!?

Fine. Now I've got to figure out what I did to break it in later versions :-(
> For SCSI, to which direction did you point? May we help you?!?
Any help appreciated. I did point in the general direction of existing code for the NCR 53C96 chip in 2.1 kernels (esp.c, mac53c96.c to name a few) as well as the existing Open/Net/*BSD code for the Mac. Though it should be fairly easy to glance the Mac bits from mac53c96.c and the m68k bits from the Amiga driver using esp.c code. A new 2.1 diff for the Mac is being prepared. Subscribe to the linux-mac...@wave.lm.com mailing list if you start work on any drivers.
