Creating ATX power Adapter
The power connector on this Zenith backplane is a Molex 03-06-1152 connector, but it is no longer manufactured, so I decided to 3d print a new one to save $15.

Log
- 2025-06-04 - Making a 03-06-1152 molex to ATX adapter, so this can be powered via ATX power supply.
- 2024-07-10 – Acquired to assist in testing the WYSE 8088 CPU board. On initial inspection, the board appeared relatively clean, though light rust was present around some screw contact points and a few random solder joints. I began the restoration process by giving it a wash with warm, soapy water.
