NOTES:
1. If an Apple 3.5 Drive mechanism (P/N 661-0345) is installed as
an internal Macintosh drive, it will require a YELLOW striped
internal cable (P/N 590-0437) in order to operate.
2. If an older version of the Apple 800K Drive mechanism
(P/N 661-0305) is installed as an internal Macintosh drive,
it will require a RED striped internal flat cable (P/N 590-0167)
in order to operate.
3. It is possible to install the recently released Apple 3.5
Drive mechanism in an external Macintosh 800K Drive or in a
UniDisk 3.5 Drive. However, you should NEVER try to install
the older verison 800K Drive mechanism in an Apple 3.5 Drive.
4. You can distinguish the Apple 3.5 Drive mechanism
(P/N 661-0345) from the older version 800K Drive mechanism
(P/N 661-0305) by its Apple and vendor part numbers. Also,
each mechanism has a different colored drive label. Refer to
the chart above for the details.
