My 512K Mac is refusing to read any disks.  Both the internal and external
drives are 400K.  I can get the internal drive to read one system disk,
but no others, and the external drive won't even accept that (even though
the disks work fine on other systems).  I am also unable to format new disks.
I suspect the alignment may have been thrown off during a recent move.  Any
ideas on how to fix this?  I have access to any test equipment I need  (scopes,
meters, etc.), but have no idea where to start.  Anyone know what to do,
or have a source of info?

thanks,
