CD 202 project

New Project , Lets make a CD 202, from these CD 200 & CD 202 parts  🙂 , I started with a  Dead CD 202 that needed a little TLC

Some incomplete Servo and Decoder PCB’s

The Front panel,  we need

• tactile switches
• Capicitors
• A New Display

A new LED without scratch

Made a new NSM4202 display , tweaking some resistors , the SMD segments are very bright
