	MOS Technology SID - Biocrawler
		MOS Technology SIDs: The right image shows a 6581 from MOS Technology, at the time they were known as the Commodore Semiconductor Group (CSG) and the left image shows an 8580 from MOS Technology.
		The SID features three-voice synthesis, where each voice may use one of four different waveforms: square wave (with variable pulse width), triangle wave, sawtooth wave and a random (white noise) wave.
		The original manual for the SID mentions that if several waveforms are enabled at the same time, the result will be a logical AND between them, but only the 8580 actually has this functionality: on the 6581 some waveform combinations will only yield silence or be close to inaudible depending on the chip revision.

	MOS Technologies - Wikipedia
		MOS Technologies, also known as Commodore Semiconductor Group, was a microprocessor and calculator company famous for its 6502 processor.
		MOS had also designed a simple computer kit called the KIM-1, primarily to "show off" the 6502 chip.
		After Commodore's bankruptcy in 1994, the Commodore Semiconductor Group (the former MOS Technology) was bought by its former management for about $4.3 million, plus an additional $1 million to cover miscellaneous expenses including EPA liens.

	Interview with Bob Yannes
		I'm afraid I haven't thought much about SID in the last 15 years...I am constantly amazed and gratified at the number of people who have been positively affected by the SID chip and the Commodore 64 (which I also designed) and who continue to do productive things with them despite their "obsolescence".
		The SID chip was my first attempt at a phase-accumulating oscillator, which is the heart of all wavetable synthesis systems.
		SID chip production was completely consumed by the Commodore 64 and by the time chips were readily available, I had left Commodore and never had the opportunity to improve the fidelity of the chip.

	MOS Technology SID - Free net encyclopedia
		The SID has Template:US patent, which was filed on February 27, 1983 and issued on July 7, 1987.
		The SID features three-voice synthesis, where each voice may use one of four different waveforms: square wave (with variable pulse width), triangle wave, sawtooth wave and a pseudo-random (but not white noise) wave.
		The original manual for the SID mentions that if several waveforms are enabled at the same time, the result will be a logical AND between them, but only the 8580 actually has this functionality: on the 6581 some waveform combinations will only yield silence or be close to inaudible, depending on the chip revision.

	MOS Technology SID in TutorGig Encyclopedia
		Together with the VIC-II graphics chip, the SID was instrumental in making the C64 the best-selling computer in history, and is partly credited for initiating the demoscene.
		The SID was devised by engineer Robert "Bob" Yannes, who later founded the Ensoniq digital synthesizer company.
		High-resolution photos of Charles Winterble's prototype C64 show the markings "MOS 6581 2082" (no R2 thus presumably an R1) which probably means that the first round of prototype SID chips were produced week 20, 1982.

		SID generates what is known as Blue Noise: a minimum frequency is set and all frequencies above this minimum are generated with equal probability; thus SID noise is biased towards higher frequencies.
		Due to time constraints, the oscillators in SID were not multiplexed, therefore they took up a lot of chip area, constraining the number of voices I could fit on a chip.
		SID chip production was completely consumed by the Commodore 64 and by the time chips were readily available, I had left Commodore and never had the opportunity to improve the fidelity of the chip.

		Due to time constraints, the oscillators in SID were not multiplexed, therefore they took up a lot of chip area, constraining the number of voices I could fit on a chip.
		My intention in designing the chip (since MOS Technology was a merchant semiconductor house at the time and sold chips to the outside world) was to be able to sell the SID chip to synthesizer manufacturers.
		Like an analog envelope generator, the SID Envelope Generator would track the Sustain level if it was changed to a lower value during the Sustain portion of the envelope, however, it would not count UP if the Sustain level were set higher.

	EL SID
		The SID chip was designed for Commodore in the early eighties by Bob Yannes, who later went on to found Ensoniq and produce much more powerful synthesis chips and stand-alone synthesizers.
		The SID chip is not known for its quietness, but Elektron have worked at improving this aspect of it, for instance using an isolated address/data buss to reduce noise leakage to the SID's audio output.
		The SID chip could have passed into history as a superior computer-games sound chip, but Elektron have succeeded in making its full synthesis capabilities accessible in a way that will be familiar to hi-tech musicians.

		It was in 2004, however, that Mos was met with both praise and (mostly) criticism for stylistically “branching out” on his ambitious sophomore album, The New Danger, a divergence from standard hip-hop protocol.
		To the beat junkies, the production may not be A-list, but Mos Def made his career off of being lyrical and truthful.
		There are some decent beats, but Mos just doesn't sound like he cares either way if the LP flies or dies.

		At the same time in mid-1981, Robert Russell (system programmer and architect on the VIC-20) and Robert "Bob" Yannes (engineer of the SID) were critical of the current product line-up at Commodore, which was a continuation of the Commodore PET line aimed at business users.
		Instead, with the support of Al Charpentier (engineer of the VIC-II) and Charles Winterble (manager of MOS Technology) they proposed a true low-cost sequel to the VIC-20 to Commodore CEO Jack Tramiel.

		MOS scores can be arrived at based on network performance measures such as jitter and latency.
		That requires monitoring the performance of the voice application, using for instance MOS, and the underlying network infrastructure issues that affect voice performance, such as latency, jitter, packet loss and echo.
		Most VoIP technology vendors supply some testing and monitoring capabilities with their products, but there are other tools on the market that will help too, Johnson says.
