What hardware base is required for the build being worked on atm (RAM/CPU etc)? I am guessing MMU+FPU will be required?
You will need an 68k CPU which supports an MMU which means you have to have a 68020 plus the additional MMU or better. An FPU is optional, but highly recommended. Plus, you need at least 32MB of memory (FastMem excluding ChipMem).
I am currently trying to install Debian m68k on my Amiga 1200 with an ACA-1230/50/64MB Fast which sports a 68030 with integrated MMU but without an external FPU without success. I am not sure whether it's related to the missing FPU (the kernel itself doesn't require an FPU and provides FPU emulation for applications requiring one) or a different bug. But we are working to get Linux back running on most 68k hardware.
Cheers,
Adrian
