===RS232 serial adapters===
Amstrad issued two [[RS-232|RS-232-C]] [[D-subminiature|D25]] serial interfaces, attached to the expansion connector on the rear of the machine, with a through-connector for the CPC 464 disk drive or other peripherals.

The original interface came with a ''Book of Spells'' for facilitating data transfer between other systems using a proprietary [[protocol (computing)|protocol]] in the device's own ROM, as well as [[computer terminal|terminal]] software to connect to British Telecom's [[Prestel]] service. A separate version of the ROM was created for the U.S. market due to the use of the commands "|SUCK" and "|BLOW", which were considered unacceptable there.

Software and hardware limitations in this interface led to its replacement with an Amstrad-branded version of a compatible alternative by [[Pace Micro Technology|Pace]]. Serial interfaces were also available from third-party vendors such as KDS Electronics and Cirkit.
