I am looking for character sheets for good old 1st Edition...self-made ones, of course, that have been created by eager fans of the game back then and maybe are still available on the net somewhere. Can anybody give me a hint where to look for resources like that? I'd be pretty happy for a helping hand

You might ask wordman (His page) if he has his 1.0 sheets still lying around somewhere.

Other than that... Sorry.
