In 1989 Psion expanded their range, previously based around variants of an 8-bit handheld computer called the Organiser, into full size laptops. The Organiser had proven to be very versatile within business, becoming the standard tool of British Telecom, Marks & Spencer and many other businesses, with barcode readers, interfaces for printers and measurement devices, and robust construction with solid-state storage. This reliance, and expertise, with solid-state storage led Psion to develop a 16-bit laptop range with no 'soft' storage options. The 80C86 based devices introduced EPOC - still in development as an embedded OS and used in PDAs and computers like the Nokia 9210, Series 5 and Series 7 - though now handled by Symbian.
Initially consisting of 3 similar systems, the MC range started with the MC200 - a 256K system with a 640 x 200 screen taking up half the space in the clamshell style top half. Unlike Psion's later PDAs, the MC had very conservative styling with the exception of the large touch-pad below the screen, and relied on good quality, especially for the keyboard and screen. The MC400 expanded the screen to 640 x 400, offering a good size display compared to contemporary machines - many of which were pure DOS and didn't offer the GUI of the MC200 and 400.
