Robert; Thanks for the nice words about my 2005 Edition of "Black's Catalog".

I've been asked by several A.C. chippers over the years to add a section on A.C. roulettes, but I just have not gotten around to doing it. I've started on such a project for my personal purposes, but there are probably a thousand or more A.C. roulettes to cover. Maybe some day... For now, Jerry Birl's book on A.C. roulettes is the standard reference on that subject.

Hopefully, my latest Edition of "Puerto Rico Chips" will be ready for distribution in early April. I've not updated that catalog in over six years and I'm almost finished with it.
