Hello,
A couple of points:
1) In general, you will find a modern ColdFire mpu more cost effective, more feature rich, and faster than a 68k device. not always, but generally.
2) MetroWerks have not been Metrowerks for several years now, and I don't know if domain metrowerks.com is still in use. There are shortcuts on the CodeWarrior site
www.codewarrior.com to request an eval licence, alternatively, you could email
license@freescale.com to get one.
Good luck
Mark
