Try 0-45-100-51. It yields a sort of pyro green color though it looks amber on screen. It is applied as a color table rather than a color layer. See the Dead Link Removed on my website.
I know that several excellent printmakers have used this method successfully. On the other hand, when I tried to help a junior college alt-process class convert to this method, we got an amazing array of weird results, so apparently it may not be as straightforward as I hoped. The sequence of steps can be programed as an Action in Photoshop which should make it nearly foolproof.
Good luck with your printing. I no longer have a 1280, but I still think it made the best digital negs I've yet seen.
