Thanks for all the responses from which I have already learned many new things.
I remember they were saying that it was based on some principle that had never
been published or patented. I also think (though not 100% certain) that it
worked in all the common transmission modes. But all they had was a brochure..

Yes, it does sound like the Richardson microscope. It has no oculars. They also
used an oil coupled condensor. Dr. Richardson sold the company and the patents
to someone else. I can try to find out who is selling them now, I know one of
their ex-employees.

Was it the Richardson Technologies instrument? This appeared to
resolve unstained mitochondria through the transmitted light path. Not
sure that it could collect a large depth of field and also thought it
was 2004 or 2006 that they were present.
Phase Focus is a different system again that can 'virtual' focus through
z once a x,y tile has been collected. This system uses coherent light
and collects the light in the transmission light path.

they were telling (not really displaying because they didn't have it with them)
about a strange microscope that achieves a very good resolution in transmission,
better than the diffraction limit, and a large depth of field. They didn't
explain how it works. I think the company was based in Germany, but I don't
remember the name. Does anyone know what it could have been or the company
name? I would like to contact them. Thanks!
