The Philips SAA1099 sound generator is a 6-voice sound chip used by some 1980s devices. [1] [2] [3]It can produce several different waveforms by locking the volume envelope generator to the frequency generator, and also has a noise generator with 3 preset frequencies which can be locked to the frequency generator for greater range.
1948 – The Trojan Minimotor begins production in Britain and becomes immediately popular. 1949 – The Mobylette is introduced in France. Its concept was "a bicycle with a nice permanent back wind". This pattern gave its name to the French slang term for moped. 30 million copies were produced until 2002, evolving much through different models ...

Johann Faulhaber (5 May 1580 – 10 September 1635) was a German mathematician, specifically, a calculator (Rechenmeister). Ioannes Faulhaberus Mathematicus Imperialis Ulmæ Natus Biography
Just like the adjacent Prannerstraße and the Promenadeplatz to the south, Kardinal-Faulhaber-Straße was an address for the aristocratic palace concentrated in the Kreuzviertel. The Königliche Filialbank (today: HVB Forum) was built in 1893/94 at the corner of Salvatorstraße. The Spreti Palais [2] was built around 1730.
Front page of a floppy disk controller data sheet (1979) A datasheet, data sheet, or spec sheet is a document that summarizes the performance and other characteristics of a product, machine, component (e.g., an electronic component), material, subsystem (e.g., a power supply), or software in sufficient detail that allows a buyer to understand what the product is and a design engineer to ...
Faulhaber's formula is also called Bernoulli's formula. Faulhaber did not know the properties of the coefficients later discovered by Bernoulli. Rather, he knew at least the first 17 cases, as well as the existence of the Faulhaber polynomials for odd powers described below. [2] Jakob Bernoulli's Summae Potestatum, Ars Conjectandi, 1713
The 2650A was a reworked version of the original layout intended to improve yield, and thus reduce cost. Speed remained unchanged at 1.25 MHz for the base model and 2 MHz for the -1 versions. The 2650B was based on the A, added two new instructions, and improved the performance of a number of existing instructions. [2]
