If someone was to have used a "film camera" to capture the eclipse would this have resulted in damage to the camera, similar to the results of having used an unprotected "digital camera"?

I say no damage. Basically, you're talking about taking pictures of the sun without a solar filter. All you would get is a very bright white light. As for damage, I don't think so.

Chances are, yes. I'd not want to risk my cameras, either film or digital.

I did it years ago. Made sure the lens cap covered the 400 mm lens I used while I wasn't shooting. Absolutely no problems. One note: the camera I used had a titanium shutter, so the odd were in my favor that nothing bad could happen.
I worry more about doing video with today's cameras. You're exposing the sensor far more than you would when taking stills. Don't have definitive answers, though.

I have several slides from a previous "once in a lifetime" solar eclipse. No internet then to create the hype. I used two pieces of unexposed film leader in slide mounts. The exposure times posed no threat to the titanium shutter. When I fried ants with a magnifying glass as a kid it took several seconds. Much shorter time here. Big difference between film and a sensor.

Depending on what kind of camera you use. Let assume you use a 35mm camera. First you will get overexposure because I think even with ISO50 and f/32 and 1/1000 sec it's still overexposed. If the camera is like the Leica which is a rangefinder with focal plane shutter you will expose the shutter to the sun for the duration of time it takes to aim the camera. During the actual exposure the shutter is safe. If it's a rangefinder with in lens shutter there is no danger because the shutter is not in focus and only the film and the back plate which is exposed for only a very short time and with small aperture. With an SLR the thing that suffers the most is the focusing screen during the aiming time at full aperture. Lots of focusing screens are plastic and with the sun in focus at full aperture for a few seconds there could be damage.

If you did not use the proper solar filter and your camera was focused on the sun then yes, you could damage the shutter curtain. Cause you are focusing a very bright light (sun) unto the curtain of your camera.

I wouldn't think there would be any damage to anything if the shutter speed is short enough. When I'm photographing the sun as it's fairly close to the horizon, I'll still use anywhere from 1/500 to 1/4000. If you're shooting the full sun overhead during the eclipse, and use the fastest speed your camera can do, it shouldn't cause any problems. Not gonna etch that in stone, but I would think it would be ok.

That can only happen with a rangefinder that has focal plane shutter like the Leica and this can happen only before and after the actual exposure. With an SLR while focusing the sun is not focused on the shutter but rather the focusing screen. When you press the shutter release the mirror goes up expose the shutter curtain for a very short time then the shutter open it's no longer exposed to the sun. On a rangefinder with in lens shutter the sun is not focused on anything before the exposure.

Yes, perhaps is it had a built in meter, tho those cells were probably rugged.... Next time... less than 100 years from to day test it out.
Holly Cats.. or Cathodes.... Microbes beat the camera people to the use of Selenium to generate electricity from light .... no microbes do not have needle meters like cameras.... "the daily dose of Se below 8.5 mg per g of biomass (<20 µM) partially stimulated the photosynthetic activity ... ."

Uh, no thanks. I'd like to keep my F in working condition. It's 46 now and I intend to keep using it.

I heard of a guy burning a hole in his lica curtain, he had left hi camera on a table facing the sun... Expensive! I have never heard any stories of damage to SLR's (film) in twenty years I was taking photo's with film. Have taken photo's of aircraft against the sun the sun through trees and ather examples where the sun was in the picture. No damage at all, not even to my eyes.
I have a Samsung Note 4 and one app measures the amount of UV exposure with the camera, it takes about ten seconds pointing at the sun and doesn't damage the camera.

Not with an SLR... unless you leave the mirror up.
