Ok, I'd like to shoot Vision 200T on my ZC1000 and have found that there are different types of cartridges.
The newer ones are one complete piece of plastic and it looks nigh impossible to open them without damaging, but I have 2 unexposed carts from Retro8 that must be the older type that they reuse for future stock, being easier to pry open, glued back together.
I have an already opened Single 8 cart in the post, and some crappy old film that came in another Super8 camera, and will be practicing asap.
I'm wondering has anyone taken the steps to complete such a process and knows the sweet spots to carefully open and load. I know that 40ft will only fit inside and I'll have to trim 10, which I later plan to cement together to use.
