Spectre Comms Serial Interface
Rare serial interface for the Amstrad CPC, manufactured by Spectre Communications Ltd.
The Spectre Comms Pack was also advertised for the ZX Spectrum, typically together with a QMOD modem.
The CPC version uses Cage Comms software in ROM. For whatever reason, the manual refers to Propak by Telemap. The Cage/Propak software is written by David Gorski and Ian Hoare.
I/O Ports are compatible with the Amstrad Serial Interface:
