     There was a problem with early versions of the 64 and the CP/M cartridge.
It had to do with timing differences between the video chip and the Z80 in the
cartridge.  Newer 64's have newer VIC chips, and the problem doesn't show up.

     Your CP/M system may also be glitched.  Does the drive light blink when
booting?
