NOTE
1 This is a standard interface for the IBM PC compatible. Note the following:
D Only two floppy disk density modes (720 Kbytes and 1.44 Mbytes) are supported.
D The DENSEL signal level is fixed to low.
D Not all commercial floppy disk drives require both +12 V and +5 V power supplies. If your
floppy disk drive requires +12 VDC, pay careful attention to its power requirements.
2 Commercial floppy disk drives are prone to compatibility problems with personal computers to
some degree. It is not guaranteed that the intelligent terminal type 2 can operate with every
commercial floppy disk drive. Machine tool builders are requested to check the operability of
the floppy disk drives they select. Keep in mind that commercial floppy disk drives are neither
dust–proof nor moisture–resistant.
3 The interface on the drive side shown above is only an example. Design an interface cable
according to the specification of the drive with which it is used.
