Hi,
Just in case this is of interest to anyone else......
As my hideaway jukebox didn't come with a keyboard/display unit (only an external wall box), I needed a keyboard and display to access the programming mode on the CCC.
As I needed some schematic/PCB practice, I built a little combined keypad display unit as shown below.
The LED's are a bit bright, but only one wire mod was required to bring it to life.
Result!
Cheers
Scott
