Well, I'm going to have to disagree, Bob.  I know of at
least one early SO2R operator who made real use of
the capability.  Now, Vic Clark tuned the second receiver
in his shack while his mechanical CQ machine cranked
away on rig one.  Now, Vic didn't make the most out
of it.  He had one transmitter and two receivers.  When
he found a new one on receiver two he'd have to take
a minute out to change bands on his transmitter.  And his
final used plug-in coils.  But it did mean that his scores
held a telling advantage.  He never missed an opening,
however short, and he always found the multipliers.

The capability to do effective SO2R operating is
dependent on technology, and technology has developed
over the years.  But my own early SO2R efforts didn't
wait for computer logging.  I used a memory keyer that
I designed and built myself to crank out the CQ's while
I tuned rig two.  On phone, W6HX built a CQ machine
out of an "Ans-a-phone" that recorded your CQ message
on the surface of a metal cyllinder.  But others were using
simple CQ machines made from tape recorders with little
tape loops hanging from the record head -- and these
were effective for both modes (with the audio keying a
relay on CW).

And the paperwork wasn't quite the huge burden that you
suggest.  While CT/NA/TRLog/etc. have made it quite a
bit easier to do SO2R, that doesn't mean that it wasn't done
effectively before computers came along.
