In the beginning of the 1990 years I have started to write Freeware-Chess
(Versions 1.XX) in Borland Pascal and DOS. Than it spent a long time in a shoe box
on a floppy disk. Any time (appr. 2005) I found it and fortunately the disk was
readable. With Delphi I have ported Freeware-Chess to windows (Versions 2.XX).
Since January 2011 Chess has been published in the internet (Versions 3.XX).
