With this serial interface, you can connect a PC to a Commodore disk drive and transfer data from the floppy to your PC. The disk drive is connected to the interface with the standard floppy cable. The connection from the interface to the PC is done with an ordinary serial cable. So the only thing you need on the PC side, is a free serial port. Why to build an interface The communication on the Commodore serial bus is very time critical. Any software that wants to communicate with a serial commodore device, has to implement some time critical low level communication routines. This kind of communication is not too difficult in operating systems like DOS, but it is very difficult in operating systems like Windows XP or Windows 2000. In addition, all the low level communication stuff has to be rewritten, as soon as the operating system is changed. The communication itself is not too well documented and its hard to write these routines.
