[BC] Negative Current Sample

[Burt I. Weiner]

Moseley made a device called a MBB-1.  It actually stood for "Magic 
Black Box"  It was a gold anodized box with two big insulators on one 
end and a terminal strip on the other end.  The sample had to be 
shunted to approximately 5 Volts for it to work correctly.  The 5 
Volt sample ran a voltage controlled oscillator emitter at one end of 
a small box inside the bigger box, and a matching receptor at the 
other end.  It did work, but it wasn't the most linear converter.
