Can you afford to read manuals and do some tries for 6 months ? Rene -- Ing.Buero R.Tschaggelar - http://www.ibrtses.com & commercial newsgroups - http://www.talkto.net

The OP wants to be a master. -- Grant Edwards grante Yow! You must be a CUB at SCOUT!! Have you made your visi.com MONEY-DROP today??

This leads to the question: What is more expensive, having a two-chip design or a one-chip design with additional SW cost ? -- 42Bastian Do not email to bastian42@yahoo.com, it's a spam-only account :-) Use <same-name>@epost.de instead !
