Identifying a V1 or V2 FSD-1 Drive JiffyDOS is available for the FSD-1 drive, however, you must determine if you have the version 1 or version 2 drive before ordering JiffyDOS. The two JiffyDOS roms are different and won't interchange between the two drives. This will involve opening up the drive so you can see the main circuit board. Remove the top cover of the drive and then look underneath the drive mechanism to see the chips. Study the pictures here to see the differences.
