/* Disc drive */
The Spectrum's DOS is more powerful than the CPC's. It can read CPC discs, Spectrum +3 and PCW discs easily. In order for the Amstrad to read Spectrum and PCW discs, it needs to have a special XDPB (Expanded Disc Parameter Block) configuration installed.
The Spectrum +3's DOS is based on the disc functions in Locoscript the CPC's DOS is AMSDOS. The Spectrum's DOS was developed after the CPCs, so clearly they saw the weakness in the CPC's DOS design and improved it.
