Very cool. It looks like Super 8 alright. I love Super 8, it's in a class by itself. My main cameras are a Beaulieu 6008s and an Elmo 1012S-XL.
It looks like you had quite a few processing artefacts, which is to be expected if you processed the film loose. If you can, get a Lomo UPB-1A developing tank. It's the one that holds a 50 feet of 8mm or 16mm film. It's really hard to learn how to load it in total darkness, but once you do, it's a terrific daylight developing tank.
Which specific film was that you were using?
