I used to have one of these when I was a kid and when I came across this one on eBay, I had to bid on it. I've seen others for sale with the instruction booklet, but mine didn't come with one. If I remember correctly, the manual teaches children how to use the toy by describing the adventures of Dataman.
Although the rear of the unit describes it as an electronic calculator, you can't use it in the sense of a traditional calculator. Punching in an equation such as 99x9 and then pressing the '=' key will not give you an answer. You must provide the answer yourself by typing in '891'. If you answer correctly, you're rewarded with a little light show on the display. If you answer incorrectly, you're given an error display and prompted with the equation again. Answer incorrectly for the second time, and Dataman will give you the right answer.
In addition to quizing yourself with equations, there are five games that you can play:
