 New and Old 101 key membranes

Solution

The IBM keyboard was made two different ways. The older version used a separate flex circuit for the LEDs. The newer version integrates the LED circuit into the keyboard membrane. We only stock and sell the newer version. To use the newer version with the older keyboard you need to remove the 4 LED traces on the right side. See attached.
