Since the sudden death of the founder and maintainer Heribert Müller,
the technikum29 computer museum is still in an interim phase. It is currently maintained by a group of
volunteers, which are presented on this page. This doesn't display the full picture, since
the big network of friends and supporters is not (yet) listed.
Bernd Ulmann (born 1970) was a collector friend of the museum's founder
Heribert Müller. He also delivered several talks at the museum during the
"Woche der Industriekultur" in recent years. His main interest are analog and
hybrid computers but he is also fond of early DEC machines such as PDP8/12/12
and early VAX systems. Other areas of interest are classic oscilloscopes etc.
He lives in Hettenhain with his wife, cats and analog computers and develops
modern analog and hybrid computers. He has a professorship for business
informatics at the FOM in Frankfurt/Main.
Dr. Jürgen Müller (born 1963) is also physicist. He is leading the
development of optical analysers for biological and pharmaceutical
research at PerkinElmer.
He spends his spare time with any kind of vintage mechanics,
electronics and computer technology.
One of his archivements in the museum is the FPGA rebuild of the
exact curcuit of the serial computer architectures of the 40s and
50s with its drum and runtime storages. At the moment he encountered
one of the few original tube computers in the technikum29, it was
immediately obvious that he will be helping to restore this
Dr. Roland Langfeld (born 1957) is physicist and held several leading
Schott AG, such
as the head of R&D, research fellow and consultant. Since early
childhood, he is interested in all kind of technology. In 1977 he
built up his first micro processor system. He collects old computers,
pocket calculators and chess computers. He is a passionate programmer
for all architectures.
Since 2016, he is working with Heribert Müller in the technikum29
for programming various computers and interfaces. Roland Langfeld
is married, has two children and lives in Frankfurt.
Sven Köppel (born 1989) is one of the three children of the museum founder
Heribert Müller. He is contributing to the
museum since more then 15 years. The focus of his work was the interfacing
of legacy paper based storage media (paper tapes and punch cards) to the
contemporary computer world. This was the foundation of exchanging
program codes over the internet and to effectively allow collaborators to
write (contribute) codes from remote. Furthermore, Sven was active in
all kind of organizational topics, such as the museum outreach and
paedagocical topics. Personally, he was living for half a decade in Frankfurt
am Main, where he obtained a physics degree in 2019. In his research, he
got an expert in high enery physics and computational physics. Since
some time, he is living with his daughter and wife in the north of
Germany (city of Münster/Westfalia; close to Hamburg).
