the **SM-B-80TE** and the [SM-B-80TC](/museum/sharp-sm-b-80tc/) training boards seem to be the first computers made by Sharp having the general public in mind.

At the time, a professional division of Sharp already sold a range of computers called **Hayac**. These boards, as well as the first MZ computer series were conceived by the Sharp parts division as a market test.

The same board concept could be found in the USA since 1985 ([MOS Kim 1](/museum/mos-technology-kim-1/), Intel SDK-85) but Sharp was one of the first manufacturer, with NEC, offering a Japan made training board.

Thanks to **Ohishi Nuboaki** and his Sharp MZ dedicated [website](http://cwaweb.bai.ne.jp/~ohishi/museum/index.htm)
