Here is a cheap way to get a power supply with a whole working system attached. Other 3000/160 : http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2764740939

I admit that I haven't followed this thread faithfully but will put my 3 cents in anyway. For one thing, I wonder if the battery is indeed simply in paralell with the power supply line. I seem to remember from back in the dark ages of computing that battery backed circuits were usually switched off when the main power came on. Maybe it is too fine a point. Given the availability of the standard cube batteries, maybe a replacement strategy is in order. I have used penlight batteries soldered together in a series to replace the PRAM battery in a pinch. I have one computer running now with a 6 volt lantern batter connected to the pram circuit. Before you get too excited, the battery was used to the point where it yeilded only 5 volts but I am not certain any harm would come from using a fully charged 6 volt source. I am not sure what clock circuit is being used but many of the early clock chips wer cmos and while cmos is very susceptible to static, they are relatively tolerant of varying supply voltages. Not sure what life to expect of the lantern battery but I am nearly certain that it will die from old age before the clock runs it down from draw. If I can figure a way I will try to make pictures of the lash-up available. There is nothing tricky about doing something like this. Just match polarity and find a way to position the battery. -- StarMax is sponsored by <http://lowendmac.com/> and... / Buy books, CDs, videos, and more from Amazon.com \ / <http://www.amazon.com/exec/obidos/redirect-home/lowendmac> \ Support Low End Mac <http://lowendmac.com/lists/support.html> StarMax list info: <http://lowendmac.com/lists/starmax.html> --> AOL users, remove "mailto:"; Send list messages to: <mailto:[EMAIL PROTECTED]> To unsubscribe, email: <mailto:[EMAIL PROTECTED]> For digest mode, email: <mailto:[EMAIL PROTECTED]> Subscription questions: <mailto:[EMAIL PROTECTED]> Archive: <http://www.mail-archive.com/starmax%40mail.maclaunch.com/> Using a Mac?
