E Sunderland, "Implementation of disc versions of tests on SRC Atlas"

Scope and Content

Approx. 30 pages of ABL program listings and comments. The engineers’ tests date from the time when a large file disc (a Data Products model 5045, of capacity 16.8 million 48-bit words) was attached to the Chilton Atlas in about February 1968. (This installation was variously known as the SRC Atlas, the NIRNS Atlas or the Chilton Atlas). Eric was sent to Chilton by Ferranti to help with the Supervisor and Engineers’ Test program modifications necessary when the file disk was attached.
