MSX Turbo-R
 
The successor of the MSX 2+ and thus has many characteristics in common. New features include: a new PCM sound chip which can produce digitized sound up to 44 KHz (in assembly language) and a new Z80 downward compatible R800 processor. The user can select the CPU (Z80 or R800) by software.
Panasonic was the only company to produce MSX 2 Turbo R systems: the FS A1. Two versions of the FS A1 were presented, the FS A1 ST and the FS A1 GT. The GT has 512 KB RAM, a MIDI interface and MSX View in ROM (MSX View is the Graphic User Interface compatible with MSX-DOS).
Panasonic stopped the production of the Turbo R when they launched the 3DO game system in 1992. They failed with this system and never returned to MSX. Lot of extensions, however, were produced by third-party companies to enhance the Turbo R, among them, an OPL4 Sound Card, a hi-res card (Yamaha V9990) with lot of hardware sprites and IDE or SCSI interfaces.

Emulator
blueMSX is a Windows based application that can emulate an MSX computer. The blueMSX application simulates behavior of the hardware components in the MSX computer with software.  Since version 2.0, blueMSX supports MSX, MSX2, MSX2+ and MSX Turbo-R software. Almost MSX machines like the ColecoVision console and the Spectravideo SVI318/328 computers are also supported.
