Diskette
Floppy disk drives were available for MSX however, in the form of a cartridge containing the disk interface electronics and a BIOS extension ROM (the floppy disk drive interface), connected to an external case with the drive. In South-America, many of these systems used a floppy disk drive, but in Europe, drives were more popular. In Japan, some MSX1 systems included a built-in 3.5-inch disk drive, like the Panasonic (previously named Matsushita) CF-3000.
