7.2 The Satellite Museums of the Historical Computers

Similarly, the Committee chose two institutions known to possess many historical
computers as the satellite museums of the future, and also a real computer museum
which will become the central office.
Satellite Museums are:

• KCG Computer Museum, Kyoto Computer Gakuin (institute)

• The Nishimura Computer Collection (personal collection of Professor H. Nishimura)

8 Articles and Series Appeared in the IPSJ Magazines

IPSJ publishes the Magazine for members of the Society monthly. From time to time,
the editorial board plans to publish historical materials.
As mentioned, the first series were about early machines contributed by the mem-
bers of the projects. Other special issues or series will be mentioned below.

8.1 Special Issue of “Less Known Computers”

In 1970's and 80's, many novel architectures were suggested, investigated and im-
plemented such as Lisp machines, data-flow computers, and inference machines for
the New Generation Computer Project (the Fifth Generation Computer). Because the
number of first generation computers was small, and because they were seen as curi-
osities, there were the opportunities for them to be described fully, except for the
commercial machines. Thus, the special issue was edited to publicize the idiosyncratic
computers which would have been otherwise forgotten. The special issue “Less
Known Computers” appeared in February 2002.
