The MOS Technology 6581/8580 SID (Sound Interface Device) was the built-in Programmable Sound Generator chip of Commodore's CBM-II, Commodore 64, Commodore 128 and Commodore MAX Machine home computers.

The SID-6581D project (or V-SID 1.0) has begun in March 2005, by David Amoros.
After he discovered the Bob Yannes’s interview (the creator of the SID chip) on internet, he decided to create an emulation of the SID behaviour in a FPGA (EP1C12 Cyclone Altera).

Texas Instruments SN76477
The Texas Instruments SN76477 "complex sound generator" is a sound chip produced by Texas Instruments. It was originally produced in 1978[1] but has since been discontinued. It was typically used as a sound effects generator in arcade games and toys.

OPLx decapsulated
Matthew Gambrell and Olli Niemitalo, 2008/04/20
We have an interest in emulation of YM3812, which is the OPL2 sound chip found in the Adlib and 8-bit Sound Blaster cards. A later derivative OPL3 is found in early 16-bit Sound Blasters. We sent one YM3812 and one YMF262 (OPL3) to MEFAS for decapsulation; the cost was around 90 USD each. They indicated that the chips would still be operational after decapsulation, but we had no need to test this. Looking at the revealed YM3812 die surface with a microscope turned out two ROM's. ...

YM2164, aka OPP (FM Operator Type-P), is an FM synthesis sound chip developed by Yamaha, related to Yamaha's YM2151. It was used in various MIDI-based synthesizers, including the Yamaha DX21, DX27, DX100, SFG-05 and FB-01, along with the Korg DS-8 and 707. The YM2164 has the following features:
    * Eight concurrent FM channels (voices)
    * Four operators per channel
    * One low frequency oscillator

The YM2151, aka OPM (FM Operator Type-M) is an eight-channel four-operator sound chip. It was Yamaha's first single-chip FM synthesis implementation, created originally for the Yamaha DX series of keyboards.

"SN76477: So klangen die '70er und '80er"  Florian Schäffer (08.05.2017)
In den frühen Videogame-Spielhöllen begnügten sich die Arcader mit recht einfachen Soundeffekten. Ein Blick auf die Schaltkreise des universellen Soundchips SN76477 von TI verrät, wie sie erzeugt wurden. ...

Der SN76477 ist ein im Jahr 1978 von Texas Instruments vorgestellter analoger Soundchip mit einem breiten Anwendungsspektrum. Geliefert wird er in einem 28-poligen DIL-Gehäuse. Mit dem SN76477 lassen sich zahlreiche Töne und Geräusche erzeugen: Musik (Miniorgel, Synthesizer), Vogelgezwitscher, Hundegebell, Pfeiftöne, Sirenentöne, Glocken- und Klingeltöne, Dampflok-, Diesellok-, Auto-, Flugzeug-Geräusche, Gewehrschüsse, Explosionsgeräusche usw. Zur Klangerzeugung dienen ein Rauschgenerator mit nachgeschaltetem Filter, ein langsamer Oszillator (L. O.) und ein spannungsgesteuerter Oszillator (VCO), der vom L. O. gesteuert werden kann. Daneben gibt es eine Anstieg-/Abfall-Steuerung, einen Mischer und diverse Möglichkeiten, die Komponenten miteinander zu verschalten. Die Einstellung der Frequenzen und Zeiten geschieht analog mit Kondensatoren und Widerständen. Zur Ansteuerung wird also kein Mikrocontroller benötigt, gleichzeitig macht die verwendete Technik die Steuerung mit einem Mikrocontroller auch schwierig. ...

Im Baukasten-Forum wurde von einem User das  Projekt "Busch Synthesizer für Philips EE" gestartet. Er hat  die SN76477-Platine aus dem BUSCH- Experimentierkasten "2073 electronic synthesizer-technik" auf eine Trägerplatine für das Philips-Experimentiersystem portiert ... Da das Anleitungsheft aus dem Experimentierkasten von Busch heute als PDF-Dokument zur Verfügung steht kann man dann fast alle darin beschriebenen Experimente nun auch auf dem Philips-System mit den Lochraster-Grundplatten und den Federnklemmen nachbauen. ...

The SN-Voice Project
If you're new to Synth DIY and have never heard of the SN76477 IC, there's a good reason - it's long been out of production. But it still exists out there in the wild - a few supply houses on the internet still list it, and it's been known to inhabit parts bins all over the world waiting for just the right application. ... Once Thomas had established the breakthrough of controlling the SN76477's VCO exponentially, attention was turned to exactly what to do with it. Ideas began to come together, and over the space of week, through a flurry of communication and breadboarding, a design began taking shape. In typical Thomas Henry fashion, a lot of functionality was gleaned out of very few parts, thus was born the SN-Voice module. ...
