Sorry, but the abacus has nothing whatsoever to do with computers. It is only a simple manually operated calculation aid. Just a portable version of the earlier sand tables, which used pebbles moved along grooves in a thin layer of sand on a table top.A computer must be capable of some degree of automated calculation, as an abacus is not capable of any calculation without a human manually performing every step it is NOT a computer.
