Re: questions and report on setting up UMAX Apus 2000 boxes
2) Most of my Apus boxes have a dead nvram battery, I need to reenter
the special settings at each poweron or power cable plug. The
nvram/battery is a RAYONAC Computer Clock Battery 840 4.5 Volts
ALKALINE. Are there any successful reports on building a custom battery
with standard Alkaline batteries, or are these batteries still available
some place? The nvram/battery is some kind of a little monster, but the
PINs are pretty standard, just like PC Speaker PINs.
I've replaced many such batteries in similar machines such as the Power
Mac 6200 and the Motorola Starmax. Because the battery is supposed to be
3.6 volts, three AA batteries is a little high and two is a little low, so
I use a four battery holder and solder a diode across the space of one of
the batteries which usually drops the voltage about half a volt.
