Re: [MiNT] EmuTOS for ColdFire

I know that, but is a CodFire between a 68000 and 68010? That is
what I don´t understand.
Something which hasn't been mentioned yet, but is very important in my
opinion when it comes to TOS/MinT compatibility:
Although running MC680xx programs on a CF v4e CPU requires a CPU
emulation library, this is not absolutely necessary the other way
round. The Coldfire instruction set is more like a subset of the 680xx
instruction set than an enhancement and, with some care (only using
adressing modes and instructions which are available on both
processors), it should be possible to write programs which run
natively on 680xx as well as Coldfire processor architectures
(although they might not run as fast on the older architecture than
they would if written exclusively for them).
