Ridai* Museum of Modern Science was built in 1991 as a museum to showcase the materials of science and engineering commemorating the 100 anniversary of Tokyo University of Science. The museum has restored the appearance of Tokyo Butsuri Gakko (Tokyo College of Science, now Tokyo University of Science) wooden building built in 1906.
There are four corners in an exhibition hall in the first floor:
(1) Memorial corner of Tokyo Butsuri Gakko:
History panels of the college, Japanese historical books, laboratory instruments, etc.
(2) Corner of the history of computing:
Counting rods, Napier’s mathematical tools, abacuses, slide rules, mechanical calculators, electric calculators, a mechanical differential analyzer, a relay calculator, electronic calculators, microcomputers, personal computers, etc.
(3) Edison corner :
Phonographs, carbon-filament bulbs etc.
(4) Science laboratory /experience corner:
Radios, solar calculators and Tiger calculators.
The corner of the history of computing displays a series of computers to follow the history of computer progress. The first is the tool for calculation such as abacuses, the next are mechanical calculators such as Tiger calculators and electric calculators, the third are larger machines including a mechanical differential analyzer, a Bendix G-15 vacuum tube computer, a FACOM 201 parametron computer, and the last are smaller ones such as microcomputers and personal computers.
The strong point of this museum is to exhibit historically important artifacts from the tools for calculation and early computers to modern machines in a room and to show the whole history of computing systematically.
