Here we have a working My Super Magic Diary JD-6500 made by Casio. Never seen one before. I would think this item is from the early 90s, made for a child and has a digital pet dog of some type. I have been collecting some selected calculators and 8 track tape players so I added this one to the collection. This device keeps the time, has an alarm, telephone directory, calendar, fortune telling and match making, pet mode and you can send messages between two of these devices by infrared light. The instruction manual is 71 pages long. Add one to your collection if you have the time.
