The Texas Instruments SN76489 is a programmable sound generator chip from the 1980s, used to create music and sound effects on computers and video game systems. Initially developed by Texas Instruments for its TI-99/4A home computer, it was later updated and widely adopted in systems like the BBC Micro , ColecoVision , IBM PCjr , Sega's Master ...
A programmable sound generator (PSG) is a sound chip that generates (or synthesizes) audio wave signals built from one or more basic waveforms, and often some kind of noise. PSGs use a relatively simple method of creating sound compared to other methods such as frequency modulation synthesis or pulse-code modulation .
The AWE64 came in two versions initially: A standard version, later re-branded as Value (with 512 KB of RAM), and a Gold version (with 4 MB of RAM, high quality 20-bit DAC and a separate SPDIF output). The earlier revision of the standard and value versions of the card (i.e. Model CT4500) had all-black jacks, but a later revision (model CT4520 ...

A world map is a map of most or all of the surface of Earth. World maps, because of their scale, must deal with the problem of projection. Maps rendered in two dimensions by necessity distort the display of the three-dimensional surface of the Earth. While this is true of any map, these distortions reach extremes in a world map.
PICO-8 is a virtual machine and game engine created by Lexaloffle Games. It is a fantasy video game console [3] that mimics the limited graphical and sound capabilities of the old 8-bit systems of the 1980s to encourage creativity and ingenuity in producing games without being overwhelmed with the many possibilities of modern tools and machines.
