Subject: Tube splitter

I'm not aware of any commercial offerings, however I've seen instances
where two co-processors have been crimped onto the same ribbon cable,
with power to each individually switched - just turn on the one you
want to use.  I'm not convinced at how good for the tube ula this
might be, though.

Something a bit more sophisticated that provides electrical isolation
between the devices shouldn't be too hard to run up with a handful of
TTL buffer chips, and that then lends itself to introducing software
controlled switching between them too.
