1.4 MB Floppy Drive Upgrade for Macintosh II - 9

 

SuperDrive, upgrade the 

Macintosh II logic board to a 

Macintosh IIx or IIfx logic 

board.

 

  Use the 1.4 MB 

floppy drive with system 

software version 6.0.2 or 

later.  Otherwise the 

Macintosh II mistakes the 

high-density drive for an 

800K mechanism.
