Rare Vintage Soviet Russian USSR VFD Scientific Calculator ELEKTRONIKA B3-18A 1978. Tested and working. Even internal Ni Cad cell batteries are charging and hold some charge. Sometimes symbol doubling on the screen after one pressed button, needs more training to work it normal again. AC adapter is included. The body has scratches on sides as pictured.
Microcalculator Electronica B3-18? was developed in 1976 and became the
first Soviet-manufactured engineering microcalculator to see serial
production. It came as a breakthrough in the realm of microelectronics.
In 1980, Electronica B3-18A cost RUB 206. The calculator was fully
portable, as it only weighed 400 g and measured 160?90?46 mm. Power
intake — 1 W or less.
The input data were entered through a 20-key keyboard. The calculator’s
special feature was the combined function key F, which made it possible
to use each key for two different operations.
B3-18A used a nine-digit vacuum fluorescent mono display for
indication purposes, with indicators enclosed within a single glass
envelope rather than scattered across the printed circuit board. The
display was capable of indicating number signs and integer overflows.
The entire calculation logic is encased in K145IP7P, a tiny one-chip MOS LSI.
Below is an excerpt about B3-18A from the article “Fantastic
Electronics” published in the science magazine “Nauka i Zhizn” (No. 10,
1976):
“This new calculator has crossed the Rubicon of arithmetics, with
mathematical capacities making a foray into the realm of trigonometry
and algebra. Electronica B3-18 can calculate squares and square roots
in a blink of an eye, produce exponentiation with eight-digit exponents
in just two steps, as well as compute multiplicative inverses,
logarithms and antilogarithms (decimal and natural), and trigonometric
functions. It does it all without using the memory unit or resorting
to the reference data. For example, in order to calculate a sine, the
calculator uses a built-in programme to perform dozens of arithmetic
operations drawing on the well-known Taylor series.
Electronica B3-18 has some 10,000 transistors, 8,000 resistors, 1,000
capacitors and 25,000 connectors. For comparison, a transistor radio
has around 100 elements, whereas a TV set employs about 1,000 elements.
All these transistors, resistors, capacitors and connectors sit
on a thin silicon plate measuring 5?5.2 mm. Just think about it: some
500 TV sets fitting into one single cell of arithmetic paper!
Incredible, indeed!”
For power supply the microcalculator can use both a built-in rechargeable battery and a line adapter serving as its charger.
