Red LED’s

The Exactra 20 and the Exactra 2000 are the only sources for the red LED PCB. As to date they have not been found in Exactra 19 calculators. Not every Exactra 20 or Exactra 2000 has the red LED boards, in fact is is rare to find that variant. There are two different colors of PCBs, the blue, and the tan/yellow. The tan/yellow boards are green except for where the LEDs attach to the board, once the excess board is cut away the PCB appears tan/yellow. There is a green stripe that runs underneath the red LED’s. The blue is solid blue the entire board.
