The Belgium company Data Applications International started in 1976 to develop a computer for Texas Instruments. This company didn't want to create a PAL-version of their TI99/4a computer. But, when the DAI was finished, they released it anyway.
Meanwhile, DAI had built this very powerfull computer. Based on an Intel 8080A with high resolution capabilities, a co-processor, pre-compiler for Basic and 3-voiced audio chip (General Instrument AY-3-8910). This all combined with a good keyboard and 48K of memory. Despite these high specs and capabilities, the computer didn't have success.
The DAI was meant to be used by the Dutch TELEAC to give a course on them, just like BBC did in the UK with their Acorn BBC-computers. The demand for the DAI was way higher than they could deliver (a 1000 were ordered and sold within a week), causing Teleac to choose for the Exidy Sorcerer (later Compudata Sorcerer). It also didn't help that the company that sold him the EEPROMs stopped delivering them.. yes, that was Texas Instruments.
The number of DAI-computers is unknown. After the company filed for bankruptcy, the company Indata continued building and selling them for another 2 years. The only difference between the two is the color label on the later Indata-machines instead of the green DAI.
The machines are considered very rare.
