	I've heard that the '026 punch needed high currents and
the available relay logic couldn't handle it, so they used an
innovative no-moving-parts replacement.  They drove the punches
with vacuum tubes.  I can't be sure of the reason, but they DID
have some glowing glass thingabobs in 'em.

I am known for my brilliance,              John Whitmore
 by those who do not know me well.
