Even better, his diode matrix circuit is actually functional: it’s a 64-byte ROM for an Atari 2600 containing an extremely simple demo program.

The diode matrix is a good learning tool, but in practice it suffers from a lack of speed due to the slow diode-resistor transitions. It also take a lot of real estate and is a nightmare to wire ...

In this paper, a novel tricolor dot matrix display system in which all the light-emitting diodes (LEDs) are modulated and encoded with audio information is presented. The novelty is on the concurrent ...

The project is an intro to Diode Matrix ROM where a signal is basically taken in and a number output on the display is given. The design consists of only semiconductors with diodes and transistors and ...

THE diode matrix is usually thought of as a component in electronic circuits using diodes of small physical size and having current-carrying capacity in microamperes. This paper describes an ...
