I am currently looking for any operating systems other than Mac OS for my 1991 Macintosh Classic M1420. Does anyone know of an OS that can run on an 8MHz 68000 and 2MB of RAM?
I think it came on a floppy disk with the book. I'll have to see if I have the floppy with my book when I get home.Where do I get this?
It's unlikely you will be able to get any variant of Linux on an original 68000.
Or the CP/M 68k ports?
Thanks, but I need to write it to floppy. How can I do this?So I was missing my XINU floppies at home, but this was on Mac GUI:

It's unlikely you will be able to get any variant of Linux on an original 68000. The 68000 had a bug where, upon invalid memory access, the processor would be left in an unstable state. This was critical for virtual memory implementations, and hence most UNIX systems made to run on a 68000 used hacks like running 2-processors side-by-side, restoring the state to a valid one on the processor one instruction ahead. Also, the classic lacks an MMU, which Linux requires. Point is: XINU is one of the very few UNIXes that will run on an original 68000 without extra hardware hacks.
Oh, okay! I have MacDisk and it works great with my 1.44MB floppies as I can just copy some files over and then erase the floppy and then copy more. Also, here's a tip: If you need to write system install disks on a Windows PC, format it with your mac and then put the disk in a windows PC (a USB floppy works fine) and then download rawwrite, then write the floppy image. It works like a champ for me.XINU won't fit on a single floppy. Follow the instructions in README.mac: copy the directory to /XINU on the system, setup Aztec C in /C, etc. You're going to need a copy of Aztec C. No idea where to find this anymore...
