It is capable of operating for 200 hours off one set of batteries, and memory is not erased by powering the unit off, so an unpowered unit can retain data for several months.A digital \"wafertape\" unit (a licensed version of the Exatron Stringy Floppy) depicted on the computer's box was only released as a prototype, reportedly because it proved too unreliable.
