   COLOSSUS. Tommy Flowers didn't put any tubes in that either. All English, so   
   they were definitely    
   valves. d   
      
   Asking how many tubes to build a computer to do all that can be done on a   
   computer is like asking how many flowers do you need to celebrate one's death   
   if you are infinitely important, where importance is measured in terms of how   
   many flowers one gets    
   brought by those still living at your funeral. Well, I'm hoping nobody will   
   waste time & money on my funeral, and so I should leave my body to medical   
   science, and, I get one chance for some bastard to say, with scalpel in hand,   
   gleam in eye, "Hey Joe,    
   here's a real nice lookin corpse..." All scientific, so there were definately   
   no flowers.   
      
   But I made a nice discrete transistor op-amp last week, and used it to make    
   a square wave gene which gave me 9.4Vpk-pk, 100 to 460kHz waves, with rise   
   time of 0.158uS, ie, 59V/uS. Then I read where there are a large number of   
   op-amps around capable of up to around 6,000V/uS. But I can't buy any of these   
   hi-falooting op-amps    
   locally, so I just used what's accumulated in my junk boxes, 2n2222 and BC327   
   and BC337....   
      
   I guess this was easier than using tubes, valves, or even flowers.
