[BULK] - Re: [TowerTalk] Vacuum tube 100 years old today

[Richard M. Gillingham]

Titan I used radar for guidance to engine cutoff..  And a RemRand Agena 
computer in the LCF to do the heavy thinking.  Lots and lots of vacuum 
tubes.  Cabinets and cabinets of 'em.  And drum memory...  Geez that was a 
long time ago.  SAC, 451SMW Lowery AFB.
