It’s probably relatively easy to get a camera. The harder part will be getting film cartridges (Kodak Ektachrome) and finding a processing lab—but a quick online search shows they’re still available.
The earliest consumer cameras had wind-up clockwork mechanism to advance the film. Later battery-operated electric motor cameras became common. One 50-foot cartridge / roll typically yields 4 minutes at 16 frames per second (fps) or 3.5 minutes at 18 fps.
Since home video came on the scene in the late 1970s super 8 was dead in the water. By 1980 I was able to cheaply purchase a very nice super 8 camera (don’t remember the make) with good optics, zoom lens, automatic exposure (but no autofocus) and electrically operated single-frame mode by which I shot many time-lapse movies of cross-country driving with the camera behind the windshield.
Editing, of course, requires at the very least a frame cutter and cellophane-tape joiners, not to mention editors, spoolers, a leader roll, film cans, and various other accessories. And what’s the point of editing unless you’re going to view the final product, which then requires a projector and screen. Personally I prefer YouTube.
