ABSTRACT:
A coin computing apparatus includes an input for converting coin values received to coin unit data for storage along with other data. This data is subsequently converted to unit data for controlling operation of the device or the dispensing of articles. The storage includes a temporary storage for storing play unit data as it is received and a permanent storage device for receiving data from the temporary storage device for updating purposes. A read/write control device is included for reading the permanent storage data to the temporary storage means following interruptions such as power failures.
