Unitrex UC 25
Brief History
Eiko Business Machine, the owner of the well-known brand Unitrex, after Japanese manufacturing was no longer profitable due to unbeatable prices from Taiwan, Hong Kong and Singapore, switched to import OEM calculators from companies in these countries. The UC models are almost identical to the Microlith calculators; their manufacturer is the same. Note that the Microlith 113G was the first to show true demands for affordable priced pocket calculators in Hungary in 1976. The UC 25 is the smallest member of the family; in addition to the Rockwell-made CPU, LED display and Klixon-style keyboard, it has only a few resistors.
