Ancient "toy computer"

Right around 1960 or '61 (I was five or six years old at the time) I was given a toy computer. I suppose it was meant to represent a mainframe (what else could it have been, given the era?) and there was a rectangular (4 x 8? 5 X 7?) array of blinkenlights on the front of it. There was also a tray in the front which accepted a small punched card. A set of these cards came with the toy. Each card had a multiple-choice question printed on it, as well as four answers to choose from, numbered A through D. Additional card sets could be purchased separately. When a card was placed into the tray and the tray was then closed, the blinkenlights would display a "random" pattern for a couple of seconds (always the same pattern) and then the array would display the correct answer to the printed question, A B C or D. It didn't take long for me to be able to read the holes in the cards, and I even "modified" a couple of them so that the toy displayed an incorrect answer. Does *anyone* remember this thing? It must have cost a few bucks back then. What was it called?
