DSCN5015.jpgAtlas Circuit Board52 viewsType 962, this is a curious board it seems to be some sord of sequenced delay line for short intervals.
The shiny plastic appearance is an uncompleted attempts to preserve it forever in a solid block of perspex. billwilladmin

DSCN4394.JPGCircuit Board59 viewsI think this might be one of the two original transistor amplifiers from the paper tape reaer, but it was long ago in the late 1970s when I took them out and replaced then with a wirewrap board with integrated circuits.

DSCN4367.JPGPaper Tape Reader49 viewsOne of the Papertape Readers from London Atlas. Rescued from an Electronics 'junk' shop after London Atlas was dismantled.
In the late 1970's I replaced its circuit boards with one I made using integrated circuits, to use it with an S100 CP/M computer.
