*part of the microprocessor 6510's characteristics:
*For a 0 the minimum is minus 0.3 Volt, and the maximum is plus 0.3 Volt.
*For a 1 the minimum is plus 2.0 Volt, and the maximum is 1 Volt above the supply voltage which usually is about 5 Volt, but whose absolute
maximum is 7.0 Volt. Note that static electricity (by friction on the carpet for example) can cause a lot of damage and must be guarded against.
