Brand: Pioneer

The Pioneer CT-757 is a model of a mid-1980s personal computer that was released by the Japanese electronics company, Pioneer. It was part of Pioneer's entry into the home computer market, which at the time was dominated by companies like Commodore, Atari, and Apple.The CT-757 had a 16-bit CPU, the NEC V30, which gave it a bit more processing power than some of its competitors at the time. It also had 64KB of RAM, which was a significant improvement over the 16KB or 32KB found on many computers in its class. The CT-757 ran an operating system called Giji-OS, which was developed by Pioneer and featured a simple graphical user interface.For storage, the CT-757 could use either a floppy disk or a hard disk. The floppy drive had a capacity of 140KB, and the hard disk option could store up to 5MB of data. The computer also had a built-in modem that allowed users to connect to bulletin board systems and access online services.One of the unique features of the CT-757 was its keyboard, which had a layout similar to that of a typewriter. This made it easier for users who were more accustomed to typing on a traditional keyboard to make the transition to a personal computer.Overall, the Pioneer CT-757 was a solid entry into the home computer market, but it failed to gain the same level of popularity as some of its competitors. This was likely due in part to the fact that it was released at a time when other companies were innovating rapidly and introducing more advanced and affordable computers. Nonetheless, the CT-757 remains a curiosity today for tech enthusiasts who are interested in the history of personal computing.
