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. billwilladminJun 14, 2015

KSCN0108b.jpgLayout of Atlas Private Tape with CC source100 viewsThis is a document which contains the allocation of blocks of varios files related to Compiler Compiler at the London University Atlas.
It shopws that the original tapes paper tapes (presumably from Manchester) were calles B through M and that the London University modifications were called M.2 M.3 and M.3+
It also shows that that magnetic tape also contained the source code of many of the compilers written in CC. All now sadly lost?

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.

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.
