Yes, but that was a spinning-disk system. The query
was about point scanners. Mojimir Petran's 'Tandem
Scanning Microscope' was made in small numbers
by a tractor maker (!) in Czechoslovakia. I believe
Alan Boyde was the first customer. It had, as you
say, a single vertical eyepiece. Tracor-Northern in
Madison (now Thermo Noran, I think) took out a licence
and soon added a proper binocular head (not really hard
to do). It was supported by their TN 8502 Image
Analysis system and you could do some quite neat
things with the combination, like taking a stereo pair
without needing to acquire an image stack.
Mind you, last time I used a modern Perkin Elmer
spinning disk system the eyepiece for the direct
ocular view was still single and very inconvenient!
I guess they don't think people will use it.

Guy et al--
I think that prior to either of these, there was a non-laser scanning instrument featuring a single eyepiece (!) and probably the least ergonomic design of any microscope. It was made by a company in Wisconsin, USA, but unfortunately I can no longer remember the name!
However, I do remember that they got the cover of Science in (if I'm
correct) 1986 showing a picture of a Golgi-stained cerebellar Purkinje cell.
