Sumlock Electronic Services (Manchester) Ltd.
This was one of a number of Sumlock local offices around Britain which were involved in marketing Sumlock-Anita calculators. When Rockwell exited the calculator market in 1976 the ex-Sumlock-Anita sales offices and service offices were then offered as franchises to those who worked in them. Some of the sales offices incorporated 'Sumlock' in their new company names and sourced electronic calculators from elsewhere which initially carried the new Sumlock name.
The Manchester branch, run by Mike Pomfret, rather than just being reduced from a mighty engineering company to a sales company decided to produce their own software line under the name Sumlock Microware[1]. They produced games for the Commodore VIC-20 8-bit home computer, shown further down. An example of one of the games is shown here:
A Sumlock compact data cassette loaded with the "Starship Escape" game for running on the Commodore VIC-20 home computer.
