From the project

Coleco Adam internal PSU board

The Coleco Adam originally shipped with a printer that contained the entire PSU for the device. It generated 12V, 5V, & -5V DC voltages for the system to run on. Now it is increasingly difficult to find the printer to go along with the system. This renders them unusable.

This project is an internal PSU that can be mounted inside the standalone Coleco Adam. If you have an Expansion Module #3 version of the Adam, it can be used outside of the system as well.
