MSX turbo R
||MSX Turbo R
MSX spawned four generations: MSX (1983); MSX2 (1986); MSX2+ (1988); and MSX TurboR (1990). The first three were 8-bit computers based on the Z80 microprocessor, while the MSX TurboR was based on an enhanced Zilog Z800 known as the R800.
The MSX Turbo R was only released in Japan.
- Processor: R800 and Zilog Z80A compatible
- R800 running at 7.16 MHz (instructions use about 4x less clock ticks than the Z80, so often quoted as 28.6 MHz when comparing with the Z80)
- Zilog Z80A compatible (embedded in the T9769C MSX-Engine) running at 3.58 MHz for backward compatibility
- Yamaha V9958 (aka MSX-Video) so the same capabilities as MSX2+
- The minimal video RAM is now 128 KB. Up to 192KB is supported.

- a new 256�212 mixed-YJK/RGB video mode with 12499 simultaneous colors
- Sound chip: Yamaha YM2149 (PSG)
- Big cartridges have either 25 or 50 pins(I need to count them on a cartridge instead of the slot to verify.)
