This is the plastic smoke-colored hinged cover piece that is found on many Casio / Casiotone models that take ROM packs. That part is often easily cracked, so here's a replacement part if you needed one. This will fit the smaller PT and MT ROM pack models, the SK8 mini sampler, and I believe the full sized CT models that take ROM packs (see measurements below to make sure). These were mostly made in the 80's but a couple of early 90's models were made to play the ROM packs as well. Measurements are 4 1/8" inches x 2 1/16" inches, with the rear of the cover not including the hinges being about 3/8" of an inch. There will be some marks / scuffs and wear on it, but no cracks or damage. This is just for one of the these type of parts that are shown in the photos, and I have a few of them available from my boxes of various parts. Thanks for looking, Check out my Store!
