NOS Diablo printer ribbon for the Adam Computer printer. New sealed ribbon but from around 1990. Just open one and did some printing on 4-18-21. See pic for how they type. They don't print as dark as when they were new but still usable. You can always reload the case with a new pancake.
NOTE Diablo ribbons cases are about 1/8" thicker then the Coleco ribbon. They will still fit but have to make sure you seat the ribbon good by turning the slack take up. Which you should be doing anyways even with a Coleco brand ribbon. If your printer head sits up higher then normal you might have to run your printer with the printer lid off.Check out my other ads. Have acquired a large collection of Adam Computer/Colecovision items from a former Coleco worker. More ads going up in future have hundreds of different items to sell. Some very rare items that you have not seen before.
