Elektor ‘Digisplay’ (1976-77)

Retronics

Published in issue 2/2009 on page 77

While cleaning out the instrument cabinet in our company shop, I came across a Digisplay unit that I built and used many years ago with considerable pleasure. At that time, I regularly put together circuits with gates, timers, counters and readouts, and it was a godsend to be able to tap 14 to 16 signals at once with an IC test clip and see the states of all these signals at the same time on a screen. In May 1976 Elektor published a circuit for connection to an oscilloscope that allowed the values of 16 signals to be read on the screen in the form of 1’s and 0’s.
