I bet itd be hard to find something like that online since its copyrighted material. Your best bet is probably to find someone who uses Jepps regularly and take a look at theirs or see if they have an old set laying around. Instrument training books like the Jepp Instrument manual also have reproductions of jepp charts side by side with NOS so you can compare. Your situation is exactly why I always recommended students start using Jepps from the get go if they can afford it. If you have the time, it might be worthwhile to see if you can get a "cheap" package from Jepp, like maybe for one state or something.
