Fixed! 82C206 cmos backup power problem.

[jpero at sympatico.ca]

Well, well,

Pinout of 82C206 made short work of confirming that did lose 
backup power.  Fault was in the 3.6V battery's plug 
contact, wiggled that plug made voltage bounce back and forth.

The board is Asus ISA-386U3Q, 256K cache installed, UMC chipset and 
had decaying CMOS battery so I removed it long ago before I put that 
board in storage waiting for a case to come along.  That time came 
when I recently picked up generic plamsa display lunch box case that 
have generic 386dx board, not cached.  Took new 3.6V nicd battery 
pack and spliced in plug to it instead of soldered pack.  The mAh 
rating is 280mAh instead of puny 60mAh.

I have questions about plamsa display stuff shortly.

Thought this chipset had seperate cmos back up supply pin.  Actually 
not, this is shared supplies with use of diode.

Cheers, Wizard
