(from Jim
Austins collection) : Elliot & Ferranti 
 I thought we were excluding larger machines. 
 
Ah, missed that bit... Ferranti did seem like an obvious miss :-)
 
 Whitecross (WX9xxx & later). Massively parallel transputer (and later
 x86) SQL machines. Doesn't do much without a Sun frontend but the
 machine itself was designed & manufactured in the UK. Sadly, the
 transputers it uses are ST rather than Inmos. I have one as a pet :-) 
 What's the difference?  
 
French vs. English. It'd be nice if the chips were british too whilst
we're being all patriotic
