L40SX repair/updates

I don't know why I like these machines so much; I'll seek counseling 
later on.

The newest machine (my 2nd) has 6MB of RAM, a dead 60MB Connor drive, a 
dead CMOS battery, a dead memory standby battery, and a dead main 
battery.  It has some scuffs and it is missing the plastic port covers 
on the back too.  Oh, and it doesn't come with a power supply.  However, 
it's generally functional.

The plan is:

Replace the Connor with an industrial Compact Flash card and adapter. 
The adapter is fairly cheap - just around $7 from Amazon.  The 
industrial Compact Flash is designed as a hard drive replacement so it 
shouldn't burn up as quickly as a regular Compact Flash card.  (Wearing 
out the memory cells is a problem, especially for a FAT filesystem.  See 
'wear leveling' for a good description of the problem.)  The machine 
will recognize a large card (1GB or more) when using Drive Overlay Software.

Replace the CMOS battery with an identical battery (Panasonic BR-2/3A). 
  A generic 3V Lithium CR123A battery fits but those are designed for 
short bursts with high power draw.  The original Panasonic battery is 
still available from Digikey at a reasonable cost.

Replace the memory standby battery with something slightly equivalent; 
it's a 3.6V NiCD pack that is only 45mAH in capacity.  That's impossible 
to find and expensive to build but I found a cordless phone battery pack 
at 110mAH that should work as a stand-in.

I am not going to repair the main battery pack yet; that is too much 
work and I really don't need portability.  But I want to start looking 
into it because NiCD cells are obsolete and the longer you wait, the 
less selection there will be.
