From the project

CR2032 to 1/2AA converter to use in various old Macintosh computers that used 1/2AA batteries as the PRAM battery.

This is intended to slot in vertically into a 1/2AA battery holder seen on many Macintosh computers for the PRAM battery. It will allow the use of the less expensive, easier to find and less leaky CR2032 coin batteries.

This is meant to be used laying flat in the battery holder like so:

There's also two extra through holes to solder wires for other uses.

The gerber, bom and component placement files are in the production folder.
