simulation of the ancient calculator (plain X version)

This program is an implementation of the original abacus, it provides the Chinese, Japanese, Korean, Roman and Russian version and can be modified to allow others.

This version was compiled without the Motif GUI widget library and thus shows limited user interface functionality. See xmabacus for the extended version.
