Psion Series 3mx
The Psion Series 3mx was the last upgrade in the popular 16-bit (SIBO) Series 3 line. Announced in July 1998, after the release of the 32-bit (EPOC) Psion 5, the 3mx is essentially an upgraded Series 3c. The 3mx comes in two models: 1 MB and 2 MB.
The Psion Series 3mx and Series 3c have a similar overall external appearance, except the 3mx sports a matte silver metallic paint covering, rather than the dark grey finish of the 3c.
The Series 3mx has a faster processor: a 16 bit NEC V30MX (80C86 compatible) running at 27.684 MHz, and a faster RS232c connection, which was boosted to 115 kbit/s. For compatibility with legacy software the processor speed can be reduced by pressing Ctrl + CapsLock.
All models of the Series 3mx came with a backlit screen, also some 3cs (mainly for the USA market) had backlit screens. The screen backlight can be switched on and off by pressing the space bar whilst the special function key is pressed.
The Series 3mx takes a CR2025 backup battery which is larger than the CR1620 that is used for the previous series 3 Psion models.
Like many other Series 3 models, the 3mx uses an infrared port which can be used to transfer data between two devices.
The capability to browse the World Wide Web on the device was also available through STNC HitchHiker, although it was only available for use with an external use. Due to the black and white screen, this was often not the most practical way of browsing the web.

Famous quotes containing the word series:
“I look on trade and every mechanical craft as education also. But let me discriminate what is precious herein. There is in each of these works an act of invention, an intellectual step, or short series of steps taken; that act or step is the spiritual act; all the rest is mere repetition of the same a thousand times.”
—Ralph Waldo Emerson (18031882)
