Hanimex BC999
From 1975, the new 900 series calculators were available. Its housing were of the same design, and their knowledge ranged from basic machines to scientific versions. The Hong Kong manufacturer of the machines is unknown. Unlike previous products, unusual colors also appeared in the grouping of keys by function, which made these devices unique not only among other Hanimex calculators, but among all calculators around the world.
In addition to the simplest BC900 model, which can only calculate percentages in addition to the four basic functions, the BCM901 with memory, the BC999 expanded with square root and register exchange capabilities, represented the household calculators; the ESR80 and ESR90 "slide rule" models were also provided with reciprocal, square, square root functions; and finally the ESR100, ESR 1010SN and ESR MASTER models also had the functions required for scientific, the ESF101 for financial calculations. These types include the same American circuits found in most similar OEM calculators of the era.
