Hi Tim,
I wrote the manual sections on the scanning, setup and a bunch of things. Jim Meyer wrote the Paint section.
I don't have a file with the manual, and I'm not sure how the former owners of Digital Creations feel about their work being put on the web.
Generally, DCTV is fairly intuitive. plug in the device, adjust, boot the software. It really helps to have a second monitor so you can work on the Amiga and see the composite output.
I had to learn by watching the engineer work on a buggy version via videotape. I haven't used one in probably 12 years.
If you send me a PM, I do have a set of video tapes I'd be willing to part with. They were done by someone outside Digital as tutorials. I might also have a second manual.
Bob
