To help train electrical engineers in digital electronics Digital Equipment Corporation (DEC) produced a digital logic trainer together with a training course. It allowed students to connect up various configurations of basic logic gates following a workbook to get a hands on idea of what it was all about.

There was a 110V version (H-500) and a 240V version (H-500-A), but all the logic ran on 5V. It came with a Computer Lab workbook (item B-350) and an assortment of 107 patch cords of assorted lengths from 2.75“ to 24.75” (item “916”). There was also a Computer Lab Teaching Wall Poster (24“ x 36”).
