 Gamma was never developed, so a few of its enhanced features were consequently pulled back into the GEC 4080.The principal designer of the GEC 4080 was Dr. Michael Melliar-Smith and the principal designer of the GEC 4060 and GEC 4090 was Peter Mackley.The 4000 series systems were developed and manufactured in the UK at GEC Computers Borehamwood offices in Elstree Way.
