With luck, your older board doesn't have the problem of a Coral Max board,
which is that the battery is soldered onto the board.  A wonderful feat of
engineering genius.  It certainly sounds like your problem is battery. 
Depending on how well you can see/get to parts on your board, it should not be
a difficult task.  Look for the battery itself, or look for a jumper on the
board marked battery, and follow the wires back if there are any.  Most of the
more recent boards (the last few years) use some form of a watch-style battery. 
(My 1990-era 386 actually has a battery pack of 4 AA's).  Once you get it out,
the mfr & model should be stamped on it.  You can probably get a replacement at
Radio Shack.
Good luck.

On the motherboard that you have, there is a coin cell battery near the
keyboard connector.  However, this has been spot-welded into place.  But
behind the battery there is a four pin connector labeled BATT for
connection of an external battery.  You can connect a battery pack here. 
You can get these packs at most any computer oriented store.

possible or not.  If it is, is it just a matter of replacing the
processor or is there more?

The Coral board cannot operate above the 60 Mhz bus speed, except the
last rev, which an operate at 66 Mhz on the PCI bus.  It was
designed around the P90.  So in theory, the new Overdrive processors 
should work.  This is something we have not tested at this time.

I am looking to add memory to a Pantera 453-0030-04 motherboard.  I
know that this board is not an EDO memory board BUT can I use EDO in
it.  I know it will not help as using 60ns when I have 70ns in there
but will it work as normal memory.

Why would I want to---  cause I can use the memory on a later upgrade
and the price is not too different now.
