@majsta

i think for starters and for a600 in particular a limited softcore without fpu is enough. good news though that the apollo features fpu. im not sure what would be the gain of adding coldfire instructions. are there any vector instructions or what? by all means do not create another incompatible target software would have to be compiled for. the different versions for different 68k cpus are already annoyance enough. we need unity and common goals, not another split.

none pushes for clock for clock 060 compatibility. a winuae type lax 68k compatibility is perfectly enough. still introducing new unique instructions may split the platform, when encouraging the newly compiled software not being full compatible with the legacy systems, that do not provide an extended instruction set.
