Talk:Belle (chess machine)

Untitled
The retrograde analysis was not done on the Belle special hardware. It was done on an ordinary PDP-11 cpu. Very little CPU grunt was required. The database had to be stored on hard disc (RAM was too small back then) and most of the time was waiting for the hard disc. In any case the special hardware was very specialised and would have needed almost a complete rebuild to do even this closely related task. A close reading of the secondary source shows they don't actually claim Belle was involved. Ken Thompson, one of the creators of Belle, did this work, which is probably where the confusion comes from. 198.142.44.242 (talk) 05:06, 2 December 2008 (UTC) -- "In its final incarnation, Belle was composed of a PDP-11/23, an LSI-11 processor, and many custom boards." This is somewhat redundant. The LSI-11 is a component (the CPU, more or less) of the PDP-11/23. 198.142.19.98 (talk) 13:21, 13 October 2011 (UTC)
