Everyone is talking about Chiptunes these days, the retro sound obtained from the games devices, and home computers of the 80s:
- Music from Game Boys –
- Commodore 64 SID chip, MOS Technology 6581 and 6582/8580R5, see SID and MOS Technology SID. See also, Video chip 6567 (VIC20) – Datasheets are here.
- The 8580 runs at a different voltage and sounds different to the 6581. The 8580 is compatible with the 6581, but requires some minor circuit changes, including a 78L09 transistor. Used in the Innovation SSI-2001, see Replica Sound Cards – AdLib, Innovation SSI-2001, and SwinSID Ultimate. See also Innovation SSI-2001: the story of one of the rarest sound cards for the IBM PC (and its replica)
- SwinSID – A replica of the SID. The Ultimate can emulate the old 6581 or newer 8580 SID. See Replica Sound Cards – AdLib, Innovation SSI-2001, and SwinSID Ultimate at 10:34. Downloads, PCB from PCBWay
- General Instruments AY-3-8910
- Yamaha YM2149F, a derivative of the AY-3-8910
- Yamaha YM3812 (aka OPL2), used in the AdLib PC sound card, early 1991 SoundBlaster v2.0 CT1350B and the Pro Audio Spectrum, see How Oldschool Sound/Music worked at 4:32. Also used in PSS-470 Yamaha keyboard. See also Ad-Lib Sound Card for the Parallel Port and Replica Sound Cards – AdLib, Innovation SSI-2001, and SwinSID Ultimate.
- Yamaha YMF262 (aka OPL3) – Backwards compatible with YM3812, and used in SoundBlaster 16, Pro Audio Spectrum 16 and ESS/Crystal Audio. See also Ad-Lib Sound Card for the Parallel Port
- Texas Instruments SN76489
- Texas Instruments SN76496 – competitor of the AY-3-8910, identical to the SN76489 but with sound in.
- From Why did the IBM PC need a sound card?, both the SoundBlaster and ZXSpectrum128k used a AY-8912, see AY-3-8910 Variants
- Intel 8253 and 8254 is a basic timer chip used by the PC internal speaker (not soundcard)
- From Building my Dream Computer – Part 2 @ 40:02 (see also @18:59):
- YM-2151 (as found in the Yamaha DX27/100 keyboard)
- SAA-1099 (Creative Labs Game blaster and sound blaster)
- PC DAC, see How the Covox and Disney Sound Source Worked.
- Covox ST (Speech Thing) –
- Disnet SS (Sound Source) –
