The man himself.	Who is Harald Feldmann ? Harald Feldmann, the (fairly) recent photograph showing him at the age of 30, started writing homecomputer software when he was 18. In 1984 a friend, Marcel Migchelsen, introduced him to the Sinclair Spectrum (In some parts of the world referred to as 'Timex 1000' or 'Timex Spectrum'). Soon Feldmann wrote BASIC programs but eventually switched over and specialized in Z80 assembly. In that year the two of them started to write Spectrum adventure games with featured the, then revolutionary, idea of synchronized events in graphics, gameplay and background film music on tapes. One of their projects involved a game design based on the film 'The Dark Crystal'. To more clearly identify their work, a name had to be invented and on one evening the combination of their first names evolved into Harald and Marcel software, hence Hamarsoft, which is pronounced Ha like in {handy}, Mar like in {marketing}, and soft as in {software}. In 1995, the name Hamarsoft was changed to Hamarsoft Research to better emphasize the commitment to research and development. The registered trademark Hamarsoft still remains.
Computer art (degraded)	In 1988, two weeks after graduating highschool and passing his final exams of a shortened, one year, course in informatics Feldmann founded Hamarsoft as a company and started to work as a consultant for several American companies in Europe. During the period that followed he developed various warehouse management and forecasting systems involving neural networks. Not challenged enough by his daily routine he began writing raytracing software and, in the process of debugging the assembly source, developed computer art. These results have been exhibited on several occasions at exclusive interior decorating companies in Europe. In 1991, through another friend, Luc Geurts, he was introduced to information theory regarding datacompression and pursued the development of new algorithms in his own, privately funded, research programme. In January 1992 he decided to build 'the world's best compressing archiver' and started to work on Hamarsoft HAP. On November 15th 1992 HAP 3.00 was released and since that time outperformed both PKZIP as well as ARJ (the market favorites) in resulting compression size. Because HAP involved top-notch assembly programming Feldmann ran into bugs present in some microprocessors of the Intel x86 family. A search for a bug-list produced no useful answers and he decided to write his own list of errors and undocumented instructions present in the x86 family. Assisted by several helpful people, the Hamarsoft 86BUGS list was born. The 86BUGS list is currently being used by many leading companies and professionals to avoid costly bugs in high-performance assembly software and compilers. These companies and institutions include leading computer hardware and software manufacturers.
