IBM had made these units with a DFP connector, but some units actually are analog units and the DFP connector is wired differently for analog use. So I took apart a DFP cable and used the connectors to make a couple of cables for the displays, one shown here was a test of the pinout I had obtained from a British car computer forum and the other was a finished cable based on that pinout.
The units are Type 4820 Model 46D (4820-46D) and are intended for a SurePOS cash register. These units have a keylock and thats it. Other units include options like a keypad, card swipe, touchscreen, etc.
Yup, only $10.
