Stofor, pronounced as in "Stow Four", is a store and forward message switching system designed by Fenwood Designs Ltd, UK in 1980.

Market and specification

Stofor was aimed squarely at the bottom end of the market and its competitors were from companies such as Chernikeeff (now John Lilley and Gillie Ltd) and Racal but Stofor was soon outselling both with ease. The Stofor range was based on a 4 MHz Zilog Z80 processor with 64K RAM and provided from 4 to 64 ports. Early models, and some later ones, were floppy disk based but later and larger versions had 10Mb Winchester technology hard disks for storage. Stofor was the only message switching system of its size to boast a custom text editor designed by Fenwood with the needs of the telex user in mind. Its main workload was in the sending and receiving of telex messages but it was also put to work in a wide range of other communications areas including fax.

The initial design was for a system that would replace a London commodity broker's antiquated telex room, containing 12 telex machines, with a computer for sending and receiving messages plus a number of VDUs (computer displays) for preparing and editing messages. The resulting Stofor system was an instant hit and many orders were placed when the broker's associates and competitors saw the system in operation. Additional options such as direct input from dedicated word processors, leased line working and several other features were soon requested and incorporated.

Users

Stofor became very popular in the City of London and was in use by banks, shipping brokers, commodity traders and insurance companies. Digital Equipment Corporation used one as the centre of its European message distribution network in Reading and others were in use by a number of household names in the food, chemical and engineering industries. Several were supplied to INMARSAT to provide telex links via satellite for ships at sea, and to the Lockheed subsidiary Memrykord, who provided international flight-planning services. [1]

Manufacture

When Stofor was born, Fenwood employed about six staff but this grew rapidly until there were forty eight, covering all aspects such design, procurement, production, software writing, sales and customer support. Sadly, with the rapid growth of fax and then the advent of email, demand for message switching systems such as Stofor died away and Fenwood moved into other markets, finally being wound up in the late 1990s. During their 'lives' Fenwood and Stofor were based in Farncombe, Godalming, Guildford; all in Surrey, UK and in Aldershot, Hampshire, UK.

Designers

Stofor was the result of work by Fenwood's three directors: John Kashel, Sales and marketing director, who came up with the concept and basic specification; Bob Fearnley, Technical Director, who designed the hardware and Tom Grainger, Software Director, who wrote the software. The original software for the product had been written by a third party but, as they let Fenwood down badly on delivery dates, Tom Grainger completed the job and eventually rewrote all the software in-house.

Commodore 64 8-bit home computer introduced in 1982

The Commodore 64, also known as the C64 or the CBM 64, is an 8-bit home computer introduced in January 1982 by Commodore International. It has been listed in the Guinness World Records as the highest-selling single computer model of all time, with independent estimates placing the number sold between 12.5 and 17 million units. Volume production started in early 1982, marketing in August for US$595. Preceded by the Commodore VIC-20 and Commodore PET, the C64 took its name from its 64 kilobytes(65,536 bytes) of RAM. With support for multicolor sprites and a custom chip for waveform generation, the C64 could create superior visuals and audio compared to systems without such custom hardware.

Fax Method of transmitting images, often of documents

Fax, sometimes called telecopying or telefax, is the telephonic transmission of scanned printed material, normally to a telephone number connected to a printer or other output device. The original document is scanned with a fax machine, which processes the contents as a single fixed graphic image, converting it into a bitmap, and then transmitting it through the telephone system in the form of audio-frequency tones. The receiving fax machine interprets the tones and reconstructs the image, printing a paper copy. Early systems used direct conversions of image darkness to audio tone in a continuous or analog manner. Since the 1980s, most machines modulate the transmitted audio frequencies using a digital representation of the page which is compressed to quickly transmit areas which are all-white or all-black.

Teleprinter Device for transmitting messages in written form by electrical signals

A teleprinter is an electromechanical device that can be used to send and receive typed messages through various communications channels, in both point-to-point and point-to-multipoint configurations. Initially they were used in telegraphy, which developed in the late 1830s and 1840s as the first use of electrical engineering, though teleprinters were not used for telegraphy until 1887 at the earliest. The machines were adapted to provide a user interface to early mainframe computers and minicomputers, sending typed data to the computer and printing the response. Some models could also be used to create punched tape for data storage and to read back such tape for local printing or transmission.

Exidy Sorcerer 1978 home computer system

The Sorcerer is a home computer system released in 1978 by the video game company Exidy. Based on the Zilog Z80 and the general layout of the emerging S-100 standard, the Sorcerer was comparatively advanced when released, especially when compared to the contemporary more commercially successful Commodore PET and TRS-80. The basic design was proposed by Paul Terrell, formerly of the Byte Shop, a pioneering computer store.

Voicemail Voice message storage and retrieval

A voicemail system is a computer-based system that allows users and subscribers to exchange personal voice messages; to select and deliver voice information; and to process transactions relating to individuals, organizations, products, and services, using an ordinary phone. The term is also used more broadly to denote any system of conveying a stored telecommunications voice messages, including using an answering machine. Most cell phone services offer voicemail as a basic feature; many corporate private branch exchanges include versatile internal voice-messaging services, and *98 vertical service code subscription is available to most individual and small business landline subscribers.

In computer science, message queues and mailboxes are software-engineering components typically used for inter-process communication (IPC), or for inter-thread communication within the same process. They use a queue for messaging – the passing of control or of content. Group communication systems provide similar kinds of functionality.

Store and forward is a telecommunications technique in which information is sent to an intermediate station where it is kept and sent at a later time to the final destination or to another intermediate station. The intermediate station, or node in a networking context, verifies the integrity of the message before forwarding it. In general, this technique is used in networks with intermittent connectivity, especially in the wilderness or environments requiring high mobility. It may also be preferable in situations when there are long delays in transmission and variable and high error rates, or if a direct, end-to-end connection is not available.
