Nintendo Famicom Disk System
the FDS and the FCD, was released on February 21, 1986 by Nintendo as a peripheral for the Nintendo Family Computer console in Japan . It was a unit that used proprietary floppy disks (called "Disk Cards") for data storage. It was announced, but not released, for the North American and PAL NES Consoles Through its entire production span, 1986–2003, 4.44 million units were sold.
The device was connected to the Famicom deck by plugging a modified cartridge known as the RAM Adapter into the system's cartridge port, which attached via a supplied cable to the disk drive. The RAM adapter contained 32 KB of RAM for temporary program storage, 8 KB of RAM for tile and Sprite data storage, and an ASIC known as the 2C33. The ASIC acted as a disk controller for the floppy drive, and also included additional sound hardware featuring a primitive wavetabel Synthesiser. The Disk Cards used were double-sided, with a total capacity of 112 KB per disk. Many games spanned both sides of a disk, requiring the user to switch sides at some point during gameplay. A few games used two full disks (four sides). The Disk System was capable of running on six C-cell batteries or the supplied AC adapter. Batteries would usually last five months with daily game play. The battery option was included due to the likelihood of a standard set of AC plugs already being occupied by a Famicom and a television.
While the Disk System was years ahead of its time in terms of a disk-format game console, the system and games both have reliability issues. The drive belt in the drive is a proprietary size, since standard floppy drive belts are too large. Until 2004, Japanese residents were able to send their systems to Nintendo directly for repairs/belt replacements, but Nintendo of America and the Pal Regions do not service them (as the system was not released in those regions). Due to a flaw in manufacturing, the old belts had a tendency to break, decompose or melt on occasion.
In an effort to save money on production, Nintendo opted to not use disk shutters to keep dirt out, instead opting to include wax paper sleeves as with the older 5.25 Inch disks The only exception to this were certain games that were specially released on blue disks (which did have shutters).
Also, error messages received when attempting to load a disk are unusually simple, to the point where it is difficult to know what the exact problem is. Most in-game error messages during loading are often displayed as 'Err. ##', with ## being the designated number for the type of error message; the most common ones are Err. 02 (the Disk System's batteries being low on power or with no batteries put in altogether), Err. 07 (Side A and B reversed when trying to load the disk), and Err. 27 ('Disk trouble', usually involving the disk surface itself). However, the error messages themselves consist of little explanation (Err. 27, for example, only give the accompanying message 'Disk trouble') and in most cases within gameplay itself, such as Zelda 2, the error message is not given at all, with only the number code shown.
Our model is in excellent unboxed condition, complete with cartridge.
