Beaut little CCR-81 data cassette recorder for the TRS-80 computer. Tested on my Coco 3 and works perfectly. TRS-80 Model I, III, 4. Has been modified with a button so you can listen to the data load in, which can be handy if you have hard-to-load cassettes.
This one appears to be one of the survivors which have not gone yellow. If you are waiting for one of these which has not gone yellow then this is what you have been waiting for. This MPI is styled like the long white case Coco 2, but it works with all Cocos including the Coco 1 and 3.
