How to write using the old script?

Corum

Is there any guide online to writing Irish in the old-fashioned manner?
I've been looking, but so far I haven't found much.

Do you mean in the Seanchló? If so it isn't really that difficult, the biggest differences are:
1. G, D and S drawn quite differently and A, T and R a bit differently.
2. Instead of writing h from lenition just put a dot on the letter before it.
3. Write 7 instead of agus.

After that the rest of the letters just get a bit of a gothic look.

See an example of the letters here:
