Sea-doo® Seascooter™2001

The smallest mass market transistor radio in the world was originally conceived and sold by Clive Sinclair in 1958 (when he was still at school).

The miniature design was smaller than a matchbox and sold serious volume of various models (including kit versions) between 1963 and 1971. Pricing was around 4.99 including earpiece accessory.

The product body construction used a standard off-the-shelf plastic box together with photo etched and polished aluminium front panel.

System 2000 Hifi set1968

The world's first slimline pocket calculator used LED (Light Emitting Diode) display technology and small hearing aid batteries.

The low power consumption needed to employ button cells with their low capcity was attained by pulsing the electronics - not recommended by the integrated circuit manufacturers, but it worked.

The keypad used a very thin plastic membrane moulding to keep the thickness down. The actual keys were the tiny buttons in the centre of each pad area.

The product was priced at 79.95 and is included in the permanent collection at the Museum of Modern Art in New York and Science Museum of London.

The Cambridge Scientific was a highly advanced calculator with an extremely small form factor for its time. The device weighed less than 99 gramms and measured only 50x111x28mm.

Scientific notation was displayed using 5 digit mantissa and 2 digit exponent. Because of the way its processor (a custom chip from Texas Instruments) was programmed, it relied on reverse Polish notation. This unusual method of mathematical problem solving meant that, for instance, to add 2 and 4, one had to enter 2, then 4, then the + symbol (no = key required).

A major factor of the Sinclair Cambridge calculator range success was its low entry level price point of only 43.95 (later reduced to 32.95 fully assembled or 27.45 as a kit).

Mass produced version of the MicroVision pocket television (world's first pocket tv set of 1966) used the smallest CRT (Cathode Ray Tube - 2") ever made. It functioned on VHF and UHF bands and was the first ever multi-band television, meaning that it could be used in nearly every foreign country worldwide. The machine weighed only 737 grams and was powered by four internal rechargeable AA batteries or from a mains adapter.

Pricing was around $400.

The Sovereign was a high-end calculator introduced in 1976, it was one of the last Sinclair calculators. The display could view 8 digits using red LED (Light Emitting Diode) display technology, and included four functions for percentage, memory, square root and square.

The Sovereign was unusual because the casing was made from pressed steel. This allowed a variety of paint and plating options, including black painted, bright chrome plated, silver plated, and gold plated. A small number of solid gold versions were made. In 1976, the chrome plated version cost 30 and the gold plated version cost twice as much.

A limited edition silver plated version, inscribed to commemorate the Silver Jubilee of Queen Elizabeth II in 1977 was also produced. The Sovereign was small and slim measuring only 36x141x12mm (power was provided by two 2.5 volt button cells).

The Sinclair ZX80 is a home computer brought to market in 1980 and is notable for being the first computer available in the UK for less than a hundred pounds (99.95). It was available in kit form, where purchasers had to assemble and solder it together, and as a ready-built version at a slightly higher cost. The machine was designed around a Z80 CPU (Central Processing Unit) and had 1K or RAM which was expandable to 16K with an optional external RAM pack. It measured just 218x170x50mm and weighed 340 grams.

The whole ZX80 development project was completed from start to finish in less than nine months.

ZX80 personal computer1980

The world's first mass market personal computer to sell under $99 was a successor to the popular Sinclair ZX80 of 1980. The ZX81 sold over 1.5 million units within two years of production and kick started a whole generation of hobbyist programmers.

The machine featured only four computer chips: the microprocessor, the ULA, the 8192-byte ROM, and a 1024-byte RAM chip (the lowest chip count rival machine of the time was the Tandy TRS-80, which featured approximately ten times as many chips).

Manufactured and sold under license by Timex in more than 70,000 stores in US alone.

The UKs best selling personal computer of all time sold many millions of units (for a period of time it shipped more units than any other computer model in the world). It featured 8-bit colour graphics,
8-bit sound, option of 16k or 48k of memory and a low cost rubber membrane keyboard. The Spectrum was among the first mainstream audience home computers in the UK, similar in significance to the Commodore 64 in the USA. Its introduction led to a boom in companies producing software and hardware for the machine, the effects of which are still seen today (the software library alone includes more than 20,000 titles). Many credit the ZX Spectrum as the machine which launched the UK IT industry. It was also considered to be the leader of the console wars in Europe throughout the 1980s which was a period of intense competition for market share between video game console and personal computer manufacturers. Pricing started at 125. Industrial design by Rick Dickinson

The world's first flat screen pocket television set was priced at 79.95 and used a 2" flat CRT (Cathode Ray Tube) with a side mounted electron gun instead of a conventional CRT. The screen was manufactured by Timex and the image was made to appear larger than it was by the use of a Fresnel lens. The unit weighed 269 grams and power was provided by a specially made six volt Polaroid flat battery or mains power adapter.

The world's first personal computer to use the Motorola 68008 processor and first mass market computer to use pre-emptive multitasking (pre-dating this feature in Microsoft Windows by 11 years). The 128K machine was the first Sinclair computer to have a full size qwerty keyboard and also included two tiny built-in Microdrive tape cartridge drives (developed by Sinclair with tapes measuring 44x34x8mm) in place of more expensive floppy disk drives. The QL had its own Windows style operating system (even though it was launched a month before the Apple Macintosh) and was also bundled with a software office suite (word processor, spreadsheet, database, and graphics) written by Psion. Linus Torvalds (creator of the popular Linux operating system kernel), owned a Sinclair QL in his youth and used it to learn programming. The product was manufactured by Samsung and entry level pricing was 399.

The worlds first mass produced electric vehicle was launched in the UK on 10 January 1985. The vehicle is a battery assisted tricycle steered by a handlebar beneath the driver's knees (chassis development was by Lotus cars in UK). Powered operation was possible making it unnecessary for the driver to pedal. Its top speed of 15 miles per hour (24 km/h), was the fastest allowed in the UK without a driving licence.

It sold for 399 plus 29 for delivery and was mass produced by Hoover in UK. Although it only sold around 17,000 units in total, it currently remains the best selling electric vehicle of all time.

The Z88 was an A4 size, lightweight, first generation laptop computer that weighed only 0.9 kg and was priced at 199. It was based on a low power CMOS version of the popular Zilog Z80 microprocessor and came with 32 KB of internal pseudo static RAM and 128 KB of ROM containing the operating system (called OZ). The memory could be expanded up to 3.5 MB of RAM. The machine was equipped with a built-in EPROM programmer with card capacities range from 32 KB to 1 MB. It was powered by four AA batteries (giving up to 20 hours of use) and used a membrane keyboard, which was almost silent in use. The machine was seen by some as the forerunner of the PDA (Personal Digital Assistant) and its built-in software included a combined word processing/spreadsheet/database application called PipeDream.

The UK's first digital mobile phone was the smallest and lightest cell phone available (weighing only 143 grams).

It predated GSM mobile phones by several years and worked using a British subscription based and location specific (Telepoint) telephone service whereby the user has to be within 100 meters of a Phonepoint transmitter to make outgoing calls (the points were the predecessor to public wi-fi and located at many destinations throughout the UK).

Additionally the phone's optional base station could be connected to a home landline and then it could be used as a cordless phone.
