The Postbank Brainbox was a Data Bank you'd receive as a gift when you
opened a kids' bank account the Dutch Postbank. I was too old at the
time to open such an account, which really did bother me. There was a
very cool TV commercial about this Data Bank.
The Data Bank itself can store schedules, names, telephone numbers, keeps the time, and can be password-locked. The battery can be removed very easily, which must have been quite a drawback between kids.
