An abacus is not a computer system as zero parts of the abacus are electrical. For the abacus to be a computer system, it has to have an input, output and process and store data. If even one of the following is not true then the device will not be considered a computer system. An abacus can not store data, as the human using the abacus will have to memorise the sequences instead of the abacus being able to memorise on its own.
