Programmable Calculators: Minor Brands

Minor Brands

Next to the four giants, Casio, Hewlett-Packard, Sharp and Texas Instruments, a large number of other manufacturers produced programmable calculators. Some are unique, one-of-a-kind designs, while others are simple OEM labels.

Classic Manufacturers

Back in the early days, several major manufacturers competed in the lucrative, but cutthroat pocket calculator market. A few survived; many didn't, and their names are now all but forgotten.

APF
A long forgotten manufacturer from the early days, APF made a single programmable model using the same chipset used in the Commodore PR-100.

Mark 90 Scientific 8+2 LED digits Keystroke entry (72 program steps) Conditionals, Branching 10 numbers Trigonometrics, Exponentials, Hyperbolics, Linear regression, Unit conversions

SC-31A Scientific 10(8+2) LCD digits Partially merged keystroke (40 program steps) 3 numbers Trigonometrics, Exponentials, Hyperbolics, Standard deviation, Continuous memory

Commodore
Before the legendary Commodore 64, Commodore was a manufacturer of office equipment. In the early 1970s, they manufactured many excellent calculators, among them some unique specialty models for mathematics, navigation, and statistics, and also two programmable models.

PR-100 Scientific 8+2 LED digits Keystroke entry (72 program steps) Conditionals, Branching 10 numbers Trigonometrics, Exponentials, Hyperbolics, Linear regression, Unit conversions

Compucorp
Arguably the most legendary of them all, Compucorp made portable programmable calculators before anybody else. Sold also under the Monroe and SUMLock brand names, these early, large machines used size "D" batteries, weighed about 4lbs each, and packed a stack of five circuit boards and a high-voltage plasma fluorescent (Panaplex) display in an incredibly compact package.

Litronix
Litronix, another early, long-forgotten manufacturer of calculators, produced a single programmable model: possibly the most ridiculous programmable calculator ever made. (The 'R' model is the same calculator with rechargeable batteries.)

National Semiconductor
It has been said that in the early days, pocket calculators represented a significant new market for integrated circuit manufacturers. It should come as no surprise, then, that a major integrated circuit manufacturer like National Semiconductor entered this marketplace with several calculator models. What is somewhat surprising is the relatively low quality and clumsy design of these early models. National Semiconductor also designed a high-end programmable calculator, but apart from a few prototypes that were sent to reviewers, this machine never saw the light of day. National Semiconductor machines were also sold under the Novus brand name and some models were also licensed to OEMs.

Other Brands

Many other major brands manufacture calculators today; some are original designs, others are OEM models.

Canon
Were it not for the relatively small number of programmable calculators produced, Canon would stand next to Casio and Sharp as yet another Japanese manufacturer that has been around since the early years, and continues to produce new calculators today. Some Canon models are also produced by other manufacturers as OEM products (although truth to tell, I am not entirely certain whether or not it was the Canon model that was the original.)

Eastern European Manufacturers

Pocket calculators were manufactured in several East Bloc countries prior to 1989, including Bulgaria, East Germany, and Poland. However, to my knowledge, only two manufacturers produced programmable models: Hungary's Híradástechnika, and the Soviet conglomerate Elektronika.

National Semiconductor It has been said that in the early days, pocket calculators represented a significant new market for integrated circuit manufacturers. It should come as no surprise, then, that a major integrated circuit manufacturer like National Semiconductor entered this marketplace with several calculator models. What is somewhat surprising is the relatively low quality and clumsy design of these early models. National Semiconductor also designed a high-end programmable calculator, but apart from a few prototypes that were sent to reviewers, this machine never saw the light of day. National Semiconductor machines were also sold under the Novus brand name and some models were also licensed to OEMs.

Canon Were it not for the relatively small number of programmable calculators produced, Canon would stand next to Casio and Sharp as yet another Japanese manufacturer that has been around since the early years, and continues to produce new calculators today. Some Canon models are also produced by other manufacturers as OEM products (although truth to tell, I am not entirely certain whether or not it was the Canon model that was the original.)
