The MC-25 converts the 10-pin system of the F5, F100, F90, F90x, N90
& N90s cameras to the 2-pin system found on the MD-4 Motor Drive
& other combinations. This is used in conjunction with the Remote
Cord MC-12A/12B, Radio Control Set MW-2 and Modulite Remote Control Set
ML-2 to provide compatability with the 10-pin system cameras.
