In 1982, the British company Grundy Business Systems released the Grundy NewBrain, a small and portable computer that was one of the first to be fully integrated into a single device for personal use.
The NewBrain was designed by Sinclair Research, the founder of Sinclair Radionics, after he started his own company. Although intended to compete with the popular Sinclair ZX Spectrum and BBC Microcomputers, the NewBrain never became as popular as these devices.
Though progressive in its day, the NewBrain lacked many standard features of modern computers, such as multitasking and a graphical user interface, and software support was limited. Despite this, the NewBrain continues to have a loyal fan base among enthusiasts of old technology, who still use and maintain it.
