Noritake CU20026SCPB-T23A (Display)

raw.githubusercontent.com_muccc_millennium_master_pics_boards_cu20026scpb-t23a-front.jpg

The Noritake CU20026SCPB-T23A is a 20 x 2 VFD Module - the display of the phone. As there is no official datasheet to the display, it seems like this display has been custom-made for Nortel.

There is a datasheet for a similar display, outlining the characters that can be displayed:

  • There is a Arduino-Sketch for testing the display here. It is - as well as the pinout and the images of the display - provided by Jim Akesons.
  • Because our test-device is missing its display, there is a arduino-based emulator, that returns the display-contents over a serial connection. You can find the code here.
