40 years ago today: Computer Weekly January 24 1974

Back to the Post Office, on page 8 our main in-depth feature presented the IT architecture. This was the shape of things to come in British telephony at the Post Office’s projected all-electronic telephone exchange concept for the 1980s, called System X. The contractor, GEC telecommunications was asked to design the equipment to last not five or 10 years, but 40 years. The IP Exchange controller had an integrated store total capacity of 64K, 16-bit words.

The article on the next slide, shows how much technology has remained the same, in spite of 40 years' progress.

The National Museum of Computing has a full copy of every print edition of Computer Weekly since our first in September 1966, and is now digitising the archive.
