Wang 300 calculator system
UvA Computer Museum catalogue nr 01.16
The Wang 300 multi-user calculator (1965) included an electronics
box (background in the picture) and one or more desktop units with
a keyboard and a numerical display. Multiplication and division
were implemented using logarithms, the transistor-efficient
calculation of which was based on a 1964 Wang patent. It could be
programmed with punched cards which were read by a 'toaster'
without any moving parts (punched holes were detected by small
contact springs, one for each possible hole position). A printer
(not shown) was also part of the configuration.
In 1965, the calculator, probably in a basic configuration, was
priced at US$ 1700.
