    "System bad 07000000" sounds like a self-test error report
indicating failure of test 07, the "Clock Test". This involves a
Read/Write test of the 'Bat RAM' clock register. Failing this test may,
as you suggest, indicate that you need a new battery. Here is some info
which may help:

007- How do I replace my GS "BatRAM battery"?

     The standard GS battery is a 3.6V Lithium type rated at 1.2AH. It
is called the "BatRAM" battery because it keeps the Battery RAM and
Clock IC going when you turn OFF power. To get to the battery, you must
pop out the Power Supply.

     If you have a ROM 03 GS, you can slip out the old battery and slip
in 'one like it'. On the ROM 01 GS, you will need a Lithium battery with
leads you can connect to cut-off leads from the old battery-- about 3/4"
each-- remaining on the motherboard. Be sure to mark the "+" lead on the
motherboard with white-out.

     Night Owl Productions used to sell a convenient "Slide-On" Lithium
battery made by Tadiran. It came with springy ends that would slip over
the cut-off leads from the original GS battery.

     Radio Shack sells a few models of 3.6V Tadiran Lithium batteries.
Mostly, these have smooth ends and are intended to fit into a holder--
for example, one model is "AA" size. Connecting an insulated size AA
holder and using a size AA 3.6V battery is one way to handle BatRAM
replacement now while making future replacements easier.

     Another Radio Shack 3.6V Tadiran Lithium battery comes as a small
rectangular insulated pack with red and black wires going to a plug.
