Changes
* DDI-1: a set consisting of the real DDI-1 (= Disk Drive Interface) and a FD-1 3" disk drive, as well as the CP/M 2.2 license and disk.
This set was for the CPC464 which didn't have a built-in [[765 FDC]] disk controller.
* FD-1: a 3" disk drive as secondary disk drive unit for the CPC664, CPC6128 and CPC464 with DDI-1
