Here is the last MSX computer ever made. It is 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.
