Electronic checkbook

Abstract

(1.) An electronic checkbook consisting of: (A.) a dedicated microprocessor which continues to perform a specific function and store the information on a day to day basis, even when not otherwise in use, (B.) Checks. (C.) Checking stubs with numbers corresponding to the checks upon which can be kept handwritten records of the balance, checks written, and deposits made. (D.) Checking account deposit slips. (E.) A folder containing all of the above . In regards to the dedicated microprocessor, four high priority routines are present which are able to interrupt the main program: (1.) When the "STOP" position is selected, it halts the processor and turns off the display. (2.) Depressing the "CLEAR" button will clear the display and second register if not in "STOP". (3.) When the "REMOVE PROTECT" button is depressed, the contents of the memory effectively become zero, if not in "STOP". (4.) When the "POST BALANCE" button is depressed, the contents of the display are added to the contents of memory, if not in "STOP". When the unit is set at "START" the contents of the memory will appear in the display.
