Electronics: The Maplin Magazine (June 1987 - August 1987)

The June-August 1987 issue of  Electronics - The Maplin Magazine introduces readers to innovative electronic projects such as a Z80-based microcontroller module for video display applications, a servo tester for radio control enthusiasts, and a capacitance tester. Additionally, it covers the complexities of machine code programming with the Z80, the evolution of television stereo sound in Britain, and provides a historical perspective on radio technology during World War II. The magazine also includes regular features like catalog amendments, classified ads, and updates on Maplin’s retail locations and offerings of the time.
