Description

Ni-Wumpf’s Gottlieb System 1 power supply is a daughter board to replace the original power supply mounted in the backbox of these games.  However, this product is made strictly as a daughterboard for the System 1 all-in-one board, though it provides all of the voltages, connections and outputs as the original power supply.  It cannot be mounted on the GTB PS bracket.

The power supply provides +5v directly to the CPU via the four 4-pin IDC connectors on the back of the board, all other connections to the power supply from the bottom board, and to the displays are designed to be compatible with the original cables.

The daughterboard is secured to the main board via two nylon posts that lock onto both PCBs to prevent detachment during vigorous gameplay.
