The Oceanic OC-118N Floppy Drive is a perfect clone of a Commodore 1541/1541-II Floppy Drive.

The strong point of this Floppy Drive is the compatibility, i would say almost total with all the software available for Commodore 64 including obviously fastLoader/original software.

There are two models of OC-118N.

The model with three dip switches and the model with two dip switches.

The difference between one and the other model is essentially the ROM; JIFFYDOS Licensed (three dip switches) / R-DOS -ROX-DOS? (two dip switches).

Between the two models there are also some differences on the mechanical part (see photo) and also seems that on the three dip switches model the front sticker is missing (not confirmed).

Autopsy:

here my collections of Commodore Floppy Drive.

The Oceanic OC-118N Floppy Drive has a external power supply, one diskette station with one read / write head and a motherboard.

On the motherboard you will find RAM and ROM memory, twice a 6522 VIA and a 6502 processor.

The Oceanic OC-118N disk drive is a smart device, reading and writing works independent of the connected computer.
