Tektronix 7D01 Logic Analyser (1978)
Back in the 70’s when engineers were bread-boarding their designs using the new fangled microprocessors they soon found that the traditional diagnostic tools were falling a little short of the job. Many found themselves in the equipment store rummaging in vain for an eight-channel storage scope. In 1973 Hewlett Packard announced their HP5000A logic analyser (US: analyzer) which was a basic two-channel machine designed for use with combinational logic and using LEDs to represent digital levels.
