   In my post on the Elk Cloner, I said you can innoculate a disk against
the Cloner V2.0 by "changing T$11 S0 B7 to 2."  This would be a BAD THING
to do!  Changing byte $B7 would change the Track/Sector list.  Actually,
since $B7 = 3 (mod 4) it won't have any effect, since only every 2nd pair
of bytes are used in the VTOC.
   What I meant to say was, change T$11 S0 B$7 [byte 7] to 2.
