Famicom

The Japanese equivalent to the Nintendo Entertainment System. It had a smaller cartridge port on the top of the unit, no lockout circuitry, and hard-wired controllers.

It also had additional hardware peripherals that were only available in Japan, including a [floppy disk drive]? that could be used to play games purchased at game kiosks in stores. The disk system was very popular for a while, and about 4 million units of the system were sold. However, because piracy was easier with floppy disks, because the disks could only hold 64 kilobytes on a side (requiring complex games to use multiple disks), and because the drive's mechanism easily wore out, the Famicom disk system was doomed.
