NEC PC8201a Battery Cartridge

This is a replacement AA battery cartridge for an NEC 8201A computer. For some reason I have two of these computers but only one battery tray.

You'll need a couple of extra parts to make it functional. I've attached pics of the parts I found on eBay:

* 2x Flat terminal connectors, 0.8mm x 2.8mm
* 3x AA Battery Positive/Negative Connectors
* 1x pair of AA battery terminals
