Spectre Comms Serial Interface: Difference between revisions

Latest revision as of 22:23, 20 August 2019

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.
