Basic
The very first version of Hiarcs was already written 1980 in PDP-11 Basic, when Mark was a 15 year old schoolboy. Subsequent versions (5 aka 0.5) were still written in interpreted Basic as well, and to compensate that speed disadvantage, Hiarcs used to be smart rather than fast. Mark Uniacke from //Now Walking, 1982-1983: HIARCS 5// :

C
End of the 80s Hiarcs was rewritten in C. In 1991 Hiarcs **1.0** was released for PCs and the MS-DOS operatig system. Subsequent Hiacs versions were compiled to run under various processors and operating systems, such as x86 and PowerPC under Windows and Mac OS, as well as mobile devices.

=Achievements= The rewritten Hiarcs soon competed in computer chess tournaments, in 1989 the 1st Computer Olympiad, and the WMCCC 1991 in [|Vancouver] where Hiarcs won the title of the //World Amateur Microcomputer Chess Champion//. Hiarcs won the gold medal (shared) at the 4th Computer Olympiad, and became World Microcomputer Chess Software Champion at the WMCCC 1993 in [|Munich]. Hiarcs won several other tournaments or got top rankings, it won the IPCCC 2007, after Rybka's disqualification in June 2011 the WCCC 2008, and the ICT 2009. Further, Hiarcs is two time World Chess Software Champion, succeeding at the WCSC 2011 in [|Tilburg], and the WCSC 2013 in [|Yokohama].
