OK, for what its worth; Lyons Brothers built the LEO because they wanted to computerize their business, but they couldn't find anyone selling commercial machines, so they went ahead and built their own. LEO, by the way, stands for Lyons Electronic Office. The LEO was actually completed in early 1951, and other companies heard about it and wanted it, so Lyons suddenly were in the computer business. Most people don't know this, but the LEO is the first commercial computer, it beat UNIVAC I to market by several months. Lyons Brothers, Elliot Automation, English Electric, Marconi, ICT, and GEC are all related, not to mention ICL. In 1969, Marconi, GEC, Elliot Automation, and English Electric merged to form Marconi Elliot Computer Systems Ltd., which kept selling the various dissimilar lines (there is some mention of AEI also being a part of this). In 1970 or 71, the company became known as GEC Computers Ltd., and some parts (I don't know what ones for sure), were combined with ICT to form ICL. Basically, GEC Computers Ltd. was all of the real-time systems, and ICL was all the data-processing systems. Somehow Lyons Brothers fits into this picture also, I'm just not sure how. ICL was first bought by an English electronics company called STC plc in 1984, then Fujitsu bought 80% of ICL in 1990. Later Nortel bought STC and then in 1998 Fujitsu bought the other 20% of ICL from Nortel. As a side note, Fujitsu also owns all of Amdahl, having excercised their option to buy the rest of the company, since as you probably know, they put up the money to start Amdahl and as such always owned a large chunk of it. I think GEC has subsided back into Marconi, but I'm not sure, the whole ICL and GEC story is a huge mess really. I hope you don't mind me taking the chance to give you more info about them than you probably wanted. BTW, I know Elliot Brothers (later Elliot Automation) dates back to 1795, and I'm fairly sure some of the other companies involved are that age or older. If anyone has more info I'd like to hear it, I have info on a bunch of models of ICL/GEC/Elliot/English Electric machines too. I'd most like to know more about ICT... ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com
