disk_error/73_DOS_MISMATCH                           disk_error/73_DOS_MISMATCH
 
 NUMBER
     73

 MESSAGE
     DOS MISMATCH

 DESCRIPTION
     DOS 1 and 2 are read compatible but not write compatible. Disks may be 
     interchangeably read with either DOS, but a disk formatted on one 
     version cannot be written upon with the other version because the format 
     is different. This error is displayed whenever an attempt is made to 
     write upon a disk which has been formatted in a non-compatible format. 
     (A utility routine is available to assist in converting from one format 
     to another.) This message may also appear after power up.
 
 NOTES
 
     Error number 73 in CBM DOS V2.6 1541.
