[sdiy] The magic of ARM

[MTG]

I think it shows how fully Motorola dropped the ball with the 68k family 
which then morphed into ColdFire and then whatever it is today.
Plus they blew a lot of money trying to get into the PC world with Apple 
and IBM on the PowerPC. I'm pretty sure the 68k was around in the 80's 
so they had a hell of a head start...
