Yes, I am aware of this, I'm on the list to buy the FPGAArcade Replay*
when it comes. However, the speed is not really that impressive yet, and
for the targets of those projects, a mere 68020 compatibility is enough,
there is no need for MMU or FPU, things that are more or less required
for linux and *bsd, so... I'd say a ~500MHz-ish fully equipped m68k is
still worthy a dream :)

(and http://www.youtube.com/watch?v=eNWLtSWXtD8 - that's a real 68EC000
running at 49.63 MHz playing video off an SD card in HAM6 as fast as it can)
Btw - I tried booting uCLinux on MiniMig, but it refuses to load, due to
lack of Fast RAM, which is understandable - MiniMig only has 2MB chipram
and 1.5MB Slow RAM - Old Minix on the other hand runs fine :)

(only 2MB, was before I upgraded with another 2MB)
