Amstrad 464 (Plus or OLD) lack CPC464: This computer lacks the extra ROM sofware disc controller hardware and [[Disc Controller]] needed the software to use a Disk Drivedisc drive. That's why external Disk Drive for CPC include such To use discs on an Amstrad CPC464 the most compatible interface is the DDI-1 (this includes AMSDOS ROM). Normally this interface came with one FD-1 3" disc drive.
Amstrad 464+: This computer lacks the disc controller hardware and the software to use a disc drive. The PCB of the 464+ is the same as the 6128+ but with the components removed. So it is possible to add all the extra components required to get a disc interface and Amstrad Action published an article about how to do this. However finding all the components is not so easy now. A DDI-1 can be fitted to the 464+, but you will probably need a conversion cable; to convert the connector on the expansion to the old edge connector on the DDI-1, but also the DDI-1 interface needs modifying to be compatible.
The 3" drives and 3" discs are not so easy to find now.
For many years now, most users connect a 3.5" disc drive. Mostly this drive is connected as drive B (and potentially with a drive switch to swap roles of drive A and drive B), but more recently some Amstrads have been modified to fit one internally, but this does require modifying the case.
