Interesting collection and story. It reminds me of the story in the the thread "Thermionic Valve" about the wartime, Phillips and Mullard. It was clearly no accident that a large manufacturer of lamp bulbs ended up making radio valves too. The "standing on the shoulders of giants" concept is very i...

I might as well ask this here and see if anyone has any ideas. Not Acorn or computing related, so apologies for that.
