Talk:5-UCO

Guy Bellairs posts about 5-UCO
See this post by Guy Bellairs, the inventor: http://groups.yahoo.com/group/ascension-island/message/329 Is this the sort of thing we can use a source? It may be a bit close to falling afoul of the WP:RS guidelines. With regard to the machine itself, Mr Bellairs says "Has anyone heard of the Apparatus Secratype, later renamed the Apparatus 5UCO? This was an on-line cipher device for five unit code, which I invented in 1943, and which was developed for the Army by the Signals research and development Establishment. In my opinion, they made very heavy weather of the development, and completely ignored the views of the inventor! Nevertheless 300 machines were built; it was used by the Army and, I believe briefly by other services, at the commencement of the Cold War. Advances in technology soon rendered it obsolete." &mdash; Matt Crypto 16:03, 23 October 2006 (UTC)

BID/30?
The code "BID/30" has recently been associated with a different machine, and given that the cite isn't hugely authoritative, I've removed this for now: &mdash; Matt Crypto 22:57, 2 November 2006 (UTC)
