It's possible to bypass the built-in floppy disk drive by connecting a standard 3½-inch drive to you Amstrad.
Hurray, your CPC is now prepared for the future ! With CPCDiskXP, you will be able to write and read Amstrad CPC disks (.dsk) from a PC.
The two parts are fitted together, maintained by the screwed floppy drive.
