A wide range of upgrades became available. The PCW 8256's RAM could be expanded to 512 KB for a hardware cost of about £50. An additional internal floppy disk drive for the 8256 would cost about £100, and installation was fairly easy. Alternatively one could add external drives, for example if a 3½-inch drive was needed. Graphical user interface devices such as light pens, mice and graphic tablets could be attached to the expansion socket at the back of the monitor. Adding a serial interface connector, which cost about £50, made it possible to attach a modem or non-Amstrad printer.
