Tabular list of desk calculators
| type or manufacturer[year of construction] | storage | attached periphery | annotations |
|---|---|---|---|
| Antia[1962] | thyratrons | - | The world's first electronic desk calculator. First generation, tube technology (especially thyratrons). Nixie-display |
| IME 84[1964] | core memory | - | The worlds's first transistorised desk calculator. Nixie-display |
| Canola 130[1965] | flip-flop | - | first calculator with "floodlight display", transistor technology |
| WANDERER Conti[1965] | core memory | - | The world's first printing electonical desktop calculator. It uses threaded ROM for very simple and solid programs. |
| FRIDEN 130, FRIDEN 132[1965] | delay line memory | - | The world's first desk calculator with display on cathode ray tube; 4 registers are displayed (with germanium transistors). Type 132 is featured with automatic square root calculation. |
| Olivetti Programma 101[1965] | delay line memory | integrated reader for magnetic cards | First desk calculator that saves programs on magnetic cards (stores up to 120 instructions). The delay line memory has a capacity of 240 Byte. Pure transistor technology |
| IME 86[1966] | core memory | remote control | Nixie-display. Lovely designed remote control |
| DIEHL Combitron[1966] | delay line memory | punchcard reader and puncher | Germany's first freely programmable desk calculator.
The complete version is extremely rare. The device's calculator features only 130 transistors. The operating system is internally booted from metallic punchcards. Rarity! |
| WANG 320 S[1966/67] | core memory | punchcard reader, manual punchcard reader | One of the world's first scientific programmable desktop calculators. Extremely rare. 2 of 4 pluggable keyboards. Pure transistor technology. Very fast computation of exponents and logarithms. |
| HP 9100 A bzw. 9100 B[1968] | core memory | incl. attached printer | First desktop calculator by HP. Totally scientific, threaded ROM. Recording programs on magnetical cards. CRT display. Transitor technology |
| WANG 700[1969/70] | 2KB core memory | Complex printer (standalone device) that can plot, too. Mark Sense Card Reader, punchcard reader, DIN A0 flatbed plotter, additionally alphanumerical keyboard, Microface, double cassette drive with formated bands. | Milestone of computer engineering! First IC-technology (DTL, TTL). Very intricately threaded ROM. Many years the world's fastest desk calculator. Big doublespaced display featuring nixie tubes (x-, y- Register), program storage on cassetts. Extremely expensive device (28.000 DM + many more than 50.000 DM for periphery). Very rare. |
| WANG 550[1971] | semiconductor memory | - | trimmed-down version of the WANG 700 - single-line nixie tubes display, thermal printer, cassette drive. |
| HP 9810[1971] | semiconductor memory | Plotter, paper tape reader, external cassette drive | Has the same logic like the HP 9100, but was built with TTL-technology. First device with LED-display (3 lines). Magnetic card reader, thermal printer |
| WANG 600[1972] | semiconductor memory | printer/plotter, Mark Sense Card Reader | Perfomance-related viewn it is set between the WANG 700 and the WANG 500. Still with threaded ROM. Programs on cassettes. |
| HP 9820[1972] | semiconductor memory | Printer, plotter, punchcard reader, external cassette drive | World's first desk calculator with algebraical language and alphanumerical display on a 5x7 dots LED-matrix, Magnetic card reader, thermal printer |
| HP 9830[1972] | semiconductor memory | Thermal printer, plotter, high speed paper tape puncher, paper tape reader | The world's first BASIC-programmable desktop calculator. Alphanumerical display for 32 chars on a 5x7-dots LED-matrix. A calculator with so much periphery is very rare |
| Olivetti Programma 652**[1973] | semiconductor memory | typewriter for output, paper tape puncher, cassette drive, band drives, hard disc drive | complete installation in the "Bauhaus" style from the 70s. The bad documentation from Olivetti is remarkable. Hard disc drive with immotile multiple head |

More desk calculators: Olympia RAE (different types, 1965): Calculator with core memory that is not programmable, germanium transistors and nixie tubes (floating point). Compucorp 322, 324 (1972): Scientific "pocket" calculator. Olivetti Programma 602 (1971): Same logic like Programma 101, but uses DTL, TTL IC-technology and semiconductor memory DIEHL Combitronic (1971): Same logic like Combitron, uses already MOS-technology (logic with only 6 ICs) but still delay line memory and booting from metallic punchcards. DIEHL Alphatronic, shift register as storage, with seperated punchcard puncher and punchcard reader (about 1973).** Canon 1614 P (1973): Programmable calculator with integrated punchcard reader and seperated printer (no manual). ** TI 59 on PC 100 printer console (1977): programmable pocket calculator with recordings on magnetic cards. HP 9821 (1973, like 9820 but with cassette drive), HP 9815 (1976) ** and many more... **) For lack of space, these devices are stored in the archive |
