In this project, an old IBM point-of-sale (POS) display is reverse engineered to display arbitrary text. The goal of this project is not entirely clear.

The display in question contains two rows of 20 characters each. The characters on the display are of the VFD type, in blue/cyan.


The interface to the display consists of 4 wires, probably an RS485 interface, possibly:

  • ground?
  • power (volts?) ?
  • RX?
  • TX?
