|MSX is an old Z80-based family of home computers which appeared in 1982 as an attempt to establish a single standard in home computing similar to VHS in video. They were popular in Asian (Korea, Japan) and South American (Brazil, Chile) countries as well as in Europe (Netherlands, France, Spain) and former Soviet Union, but they are virtually unknown in USA. Although MSX standard quietly died to year 1988, the world got to see MSX2, MSX2+ and TurboR extensions of it.|
Hardware-wise, MSX represents a hybride of a videogame console and a generic CP/M-80 machine. Its heart is a Z80 CPU working at 3.58MHz in the base model. The clock frequency has been doubled in the TurboR. The video subsystem is built around a TI9918 or TI9928 VDP chip also used in Texas Instruments' TI-99/4 computers, ColecoVision, and Coleco Adam. In the later MSX models this chip has been upgraded to V9938 (MSX2) and V9958 (MSX2+ and TurboR). The latest version of it is V9990. The audio system is handled by AY-3-8910 chip by General Instruments, same as the one used in Sinclair ZXSpectrum128 audio. AY-3-8910 provides 3 channels of synthetized sound, noise generation, and two general purpose parallel IO ports which are used for joysticks and some other things in the MSX design. Due to their hardware structure, MSX machines were perfectly suitable for games and there is a lot of good games either written or ported to them.
