Axon1.0 DOS - 20 years ago:

                     axon

The very first version of Axon was developed during 1991/92 using PDC Prolog 3.30 and BGI (Borland Graphics Interface) . PDC Prolog is also used in all subsequent versions of Axon. The objective of the software has also remained unchanged - to provide an environment that supports the thinking process. The following comparison remains valid since the first version.
