1983年3月，由Texas Instruments（TI）研发的TI CC-40便携电脑问世。这款便携电脑采用的是TI公司自己研制的70C20 （2.5MHz）处理器，6K-18K的内存，单色液晶显示器。这款便携电脑在当时的绝对优势在于，重量只有600g，采用4颗AA电池供电的时候能够持续运行200个小时！

不过很遗憾的是这款计算机有一个十分严重的缺陷，那就是无法存储资料。也就是说，你的文件无法保存在媒介上，只能暂时保存在电池供电的RAM中。虽然它提供了磁带数据存储系统，但是该系统的稳定性极其糟糕。使得这款娇小的健儿，在市场上很快就销声匿迹。它的改良型号CC-40+虽然有样机问世，却从未推出市场而惨遭夭折。

详解编辑本段回目录
Texas Instruments (TI), once the world's largest semiconductor manufacturer, introduced the Compact Computer 40 (CC-40) in 1983. The CC-40 was very 'cute', and TI's first entry into the portable computer market.
Sales were slow, partly because no mass storage device was available. The promised Wafertape Digital Tape Drive turned out to be far too unreliable for mass production. You can't even save files to a cassette recorder, like most inexpensive computers. The only method of loading files is by inserting a 'Preprogrammed Solid State Software' cartridge, but they are read-only, so you still can't save any data to them.
One redeeming feature is that the data stored in memory (RAM) doesn't get erased when you turn off the computer. The CC-40 is efficient enough that the 4 "AA" batteries can maintain the memory for many months. Even when turned on and being used, the CC-40 will run as many as 200 hours before the batteries run down.
