7-27-96. FiTi: "Colossus faces rebirth into a world of dispute." The man behind the resurrection of Colossus is Tony Sale, a computer expert and former MI5 operative who once worked for Peter Wright of "Spycatcher" fame. Its reconstruction, now in its final weeks, is not merely an act of homage to the mathematical supermen of Bletchley who hastened the Allied victory over the Nazis. Neither is it just a triumph over the official secrecy in which the machine was cloaked until a few years ago. It is a working demonstration of Sale's contention that Colossus was the world's first computer. So sophisticated was the machine intelligence at Bletchley Park that the very existence of Colossus was not revealed until 1970, according to Tony Sale. After the war the government ordered 10 Colossi to be broken up -- some say as part of an intelligence deal with the Americans. Gripped by a desire to assert the claims of Colossus, the former MI5 man asked GCHQ to reinstate his security clearance so he could work on the project. The parts could be found in any British telephone exchange up to the 1970s. Yet it took until 1992 to get all the electronics declassified. Only last November was Sale allowed to demonstrate the machine's ability to break the Lorenz wheel settings. Even today members of the public are forbidden to operate Colossus: some of its codebreaking algorithms are still, it seems, a secret. ----- http://jya.com/coloss.txt (15 kb) COL_oss
