sound chip on 8-Bit computers the AY3-8912
768-Bit computer sound generation
In the 1980's a lot of the 8-Bit micros available used the AY3-8912 sound chip to generate music and sound effects. This was especially useful for games programmers (and games players!) The sound chip was used in machines such as the Oric 1, ZX Spectrum 128 (and plus 2, plus 3), the Amstrad CPC range and various MSX computers.
Early gaming consoles also used the AY sound chip (such as the Vectrex) allowing developers who knew the hardware to produce music and sound on a broad range of machines.
Due to it's flexibilty and 3-channel output it was suitable for music making during the 1980's. Amazingly, a limited stock of chips are still available allowing vintage machines to be repaired if the sound capability has failed.

Examples of music
There were some games that were well known for utilising the AY sound chip well, such as the classic arcade game Outrun, The Addams Family, Hard Drivin' and Robocop.
Of course there were many more, too many to mention in fact, but retro gamers will no doubt remember the music from those titles. Below are some videos showing good examples of what could be produced by talented developers and musicians with the chip.

Games consoles
The AY chip was not solely restricted to home computers. It was also used in home gaming consoles such as the Intellivision and the Vectrex - highlighting the sound chips versatility and it's popularity.
The AY chip was a good way to incorporate 'arcade style' music and sound effects into the home gaming systems. As we all know, good music and good in game sound could really make a game just that little bit better. A nice opening theme tune, haunting in game music and good meaty explosions could turn a game from being merely 'good' to being great.
Below are some examples of good sound and music that enhanced the gaming experience on home consoles.

Delight for Spectrum gamers
When the ZX Spectrum 128 was released it was delight for the dedicated base of gamers on Sinclair's premier machine.
The previous versions of the Spectrum had a relatively poor sound chip (it was basically a single channel 'beeper'). Clever programmers had managed to produce synthesiser style sound and sometimes approximate two and three channel music on the beeper (how they managed it was a minor miracle) - but now true three channel music and arcade style sound effects could be produced on a ZX Spectrum computer.
The AY sound chip added to the quality of Spectrum games - and some older games were re-issued with hight quality music and sound effects. The face of Spectrum gaming changed with the arrival of the trusty AY.
Who can imagine Outrun without the classic 'Splash Wave' or 'Magical Sound Shower'? How much better would Space Harrier have been on the ZX Spectrum with the seminal arcade music included during play? Robocop is one title that is well remember for it's music as well as it's gameplay. The importance of sound and music in games cannot be underestimated.
As you can hear in the video - although clever programmers worked miracles with the ZX Spectrum's single beeper (this single channel version of Moonlight Sonata is a good example)- the AY sound chip was a blessing to our ears and enhanced many of these classic games!
