Yes, I vaguely remember that MOVEs to the status register weren't allowed any
more in normal mode with the 010, only in supervisor mode. They introduced a
'partial' register for this (SR vs CCR ?) to save the bits that were
'precious'. Consequently, a lot of software (at least the ROMs of the Amigas)
had to be patched.
