Thanks. > > Michael Niehaus > Ball State University > UUCP: ..!{uunet,pur-ee,iuvax}!bsu-cs!mithomas There is a utility application that came with the CMS hard disk (I believe) on my Mac II called ZapRAM. It is specifically designed to handle the problem of being able to reset the Parameter RAM on a Mac II since the 'long life battery' is 'soldered' to the board. You may be able to get a copy from a local dealer. If not, let me know and I'll send you a copy of mine if the authors of ZapRAM have no objection. I haven't had a real occasion to use ZapRAM, but did set Parameter RAM with some new values, then ran ZapRAM, and displayed PRAM after that. The defaults were restored as advertised.
