The Microwriter was a hand-held portable word processor sold in the early 1980s by Microwriter Ltd, of London, UK.

The Microwriter MW4
The 'MW4' Microwriter is believed to be the only model sold in any significant quantity. The 23 cm x 12 cm x 5 cm device comprised:
- A six-button chording keyboard.
- A single line LCD display.
- An 8 bit microprocessor.
- Complete Word processing software in ROM.
- 16 Kbytes of RAM.
- Rechargeable Nickel-cadmium batteries - sufficient to run the device for several hours.
- Various interfaces (see below).
This device was capable of allowing the user to enter and edit several pages of text - and by connecting a printer to the RS-232 serial port connector, documents could be printed without the aid of a separate computer.
Keyboard
The innovative keyboard used one button for each finger and two for the thumb of the user's right hand. The five buttons that lay immediately beneath the hand were pressed in different combinations to generate the letters A through Z. The second thumb button was used to toggle through a range of modes that would allow the user to switch case, enter numbers, insert punctuation and even add ASCII control characters, that could be used in editing the document being prepared. To type a letter 'T', for example, the user would tap the top thumb button to shift to uppercase, then chord a 't' by pressing the index finger and ring finger buttons simultaneously.
This unusual keyboard was surprisingly easy to use - the manufacturers claimed that most people could learn to use it in just a couple of hours. With a little practice, it was possible to become a faster typist with the Microwriter than with a conventional keyboard, providing that what was being entered was just text. Things slowed down a lot if a substantial number of special characters had to be entered using the 'shifting' mechanism.
Learning the chords for the basic letters and numbers was facilitated by a set of flash-cards that showed simple mnemonics for each character.
External ports
At the top end of the unit was a 25 pin D-type connector providing an RS-232 port, an interface to an audio cassette player for saving and restoring files and a small white on/off button. At the other end was the connector for the battery charger and a 37 pin D-type connector that could be hooked up to an optional external unit to allow the Microwriter to be connected to a television and thus to perform full-screen editing. The serial port could be used to connect the Microwriter directly to a printer - or to allow it to be plugged into a computer to function in place of the conventional keyboard.
The fate of the Microwriter
The Microwriter was an innovative product, and was endorsed by writer Douglas Adams. Despite the fact that there was no similar product on the market, the Microwriter was not a great success, and ceased production in 1985. It is likely that the concept of a chording keyboard put off many potential customers, although users of the device reported that, in practice, they could learn to use it to a acceptable standard after just one or two hours of training, with proficiency taking a few days.
A cut-down version of the Microwriter, known as the "Quinkey", was sold as a keyboard add-on for the BBC Micro computer. It came with a game that helped the user to learn the chords. There were two versions of the interface software, one optimised for entering BBC BASIC commands, the other for word processing.
A modified five-key version of the Microwriter chording scheme was later provided on the 'AgendA' handheld device, an early PDA, which also used a main normal keyboard. A modern equivalent, the "CyKey", is currently sold by Chris Rainey, co-inventor of the Microwriter. This is an ambidextruous chord keyboard, with three groups of three keys, which can be used as a controller keyboard for PCs or a PDA. Unlike the original Microwriter it does not include built-in software.
