David: Sounds like negative advertising to me. I've always found that to be counterproductive. I hope you can tell us if this was a two pin or three pin job. I haven't heard the pros and cons of that. I've thought long and hard about Wapin. There are a couple of theories in an obscure part of my brain as to why it works or doesn't work as the case might be. If I get this formalized and proved and wrote it up and copyrighted it, do you think I could get a royalty from Wapin to use it in some positive advertising? I'd be happy with about $35 (only about 10 percent of their license fee) per sale. (G) Carl Meyer Assoc. PTG Santa Clara, California cmpiano@attbi.com ----- Original Message ----- From: "David M.
