[Leica] noctilux factoid of the day

[jhnichols at bellsouth.net (Jim Nichols)]

Have you guys never heard of Friden or Marchant desktop calculators?  These 
were way more accurate than my old K&E slide rule.  Friden even made one 
that calculated square roots.  All of the checkpoint calculations for our 
digital data reduction programs were done by hand by some talented ladies 
using these machines.
