Gentlemen,
From the responses that I’ve gotten, I see that I need to be more specific.
To see a picture of the component that is no longer available:
Select “Display/Timer/Audio” tab.
Select “Digital Timer” tab.
Select “Display Panels” tab.
The picture of the green printed circuit board is the item needed to connect the serial data stream from the laptop running Gliderscore to the LED display panels.
That is what is no longer available.
