This machine was released only in Japan and is named he ultimate MSX-machine. Therefor this machine is imported a lot by MSX-lovers.
Unlike it’s Z-80 based precursors, this machine contains a RISC-processor. With this the machine can act much faster while keeping backwards compatible with the old Z-80.
A special feature of this Turbo-R is the addition of the FMPAC chip. This chip provides much better sound and music capabilities.
The Turbo-R is, as common for MSX, fully backwards compatible.
