Is there anything like a slide projector or display for unmounted slides?
Possibly a magnifying light table? Or a microfilm-style viewer?

Bonus points for ability to project or magnify medium format film!

I can remember from my school or university days seeing a projector
which took rolls of unmounted film - a bit like the slide duping film
roll attachment for the Canon (and probably other makes) auto bellows.
That has a holder at each side for the uncut film rolls; can't recall
how you move the film along. I imagine you have to be careful not to
scratch the film.

Don't know any firm details at all, sorry, all I know is something like
it existed in the 60s/70s. It seemed from memory to be big enough to be
roll film sized.

You could always contrive to make one from a large/medium format
enlarger, at a pinch. Just check it can go to infinity focus to get a
decent projection distance.

Ahhh Yes, the school days. I remember the "automated" ones that had a
cassette player. A tone on the tape would cause the projector to flip to the
next frame. I believe the film traveled vertically meaning it probably used
an 18x24mm frame format so this wouldn't work so great with 35mm 36x24mm
frame format.

I recall having a "Scooby Doo" viewer that ran on 4 C or D cells and
projected on to a small screen : )

They refer to this as a "film strip" projector. We had them back when I
was in elementary school. There were also desktop film strip viewers.

I remember that the film strip could get loose, and it was about the
length of a 36 exposure roll of film. I would bet, for the educational
market, that they used one of the tougher film bases, and probably
lacquered over the emulsion, for scratch resistance.

Ciao!

In the UK they were made by Aldis if my memory's correct. Haven't seen one for
decades.

Thanks everyone. I'll check out secondhand sections, garage sales,
and Ebay. Seems like something that projects cut strips of slides,
either 35mm or 120, would be useful nowadays. Maybe the Scooby-Doo
projector can be rereleased with the new movie!

Had a little ol' biddy of a history teacher who kept calling it a "strip
film" projector.

I wonder how a regular overhead projector would work for larger/medium
format for the gent with the question?

AIUI, they normally use either a fresnel lens, or a large single element
condenser-type lens with pretty dreadful chromatic aberration.

Not on the "Main Avenue," none of the slide projector manufacturers
offer anything to project rolls of film or even just film strips.
I looked at Kodak, Zeiss, Leitz, Rollei, Kindermann, Braun and
Reflecta and I have always a roughly current view at what they
manufacture or have manufactured (Zeiss is out of slide projecting
business.)
