      The rensha turbo (auto fire function) is basically a dumb implement to fill the second FD bay in only one Floppy models, remark the 2 floppy model haven't it.

      Also those models are 'unofficialy' imported to spain with the psu changed to 220 50Hz and a app in disk for display the tilde (Ñ) an are imported by a MSX spanish magazine , the price imported reaches a low end pc machine and is higher than an amiga or an atari. In fact, this model killed the standard in spain because people saw the "logical evolution" ridicously expensive

This is a [MSX 2+](/museum/msx-2-291/) computer. It'a kind of [Wavy 35](/museum/sanyo-wavy-35/) with a built-in 3.5" disk-drive (720 KB).

No great enhancements over the [MSX 2](/museum/msx-2/), the MSX 2+ has 19268 colors instead of 512, some more graphic / KANJI resolutions and the FM-PAC cartridge is included, providing 9 channels of FM sound without drums or 6 channels FM sound with 5 FM drums.

The Sanyo Wavy 70FD features the Rensha Turbo, which is a built-in auto-fire system. The repetition speed can be adjusted with a slider. There is also a PAUSE button, which hangs the system. Another special feature of the Wavy 70FD is the built in XBASIC language. It's also called KUN BASIC/KUN COMPILER, but it's real name seems to be MSX BASIC KUN (which means Mr. MSX Basic)

There was also a **Wavy 70FD2** with two built-in 3.5" disk-drives (see pictures section). Another difference with the Wavy 70FD is apparently a 256 KB JIS-1 and JIS-2 ROM.

MSX2+ computers were only produced by Panasonic, Sony and Sanyo. They were only available in Japan...
