It must be noted that the majority of profits are to be made through the production and development of software while the actual assembly of the computer is less profitable.
The processor card, keyboard, monitor and cassette drive were all mounted in a single metal case.
InByte referred to the PET design as "the world's first personal computer". The machine also included a built-in Datassette for data storage located on the front of the case, which left little room for the keyboard.
The was announced in June and the first units were shipped in mid October Although the machine was fairly successful, there were frequent complaints about the tiny calculator-like keyboard, often referred to as a " Chiclet keyboard " due to the keys' resemblance to the popular gum candy.
This was addressed in the upgraded "dash N" and "dash B" versions of thewhich put the cassette outside the case, and included a much larger keyboard with a full stroke non-click motion.
Internally a newer and simpler motherboard was used, along with an upgrade in memory to 8, 16, or 32 KB, known as the N-8, N or N, respectively. The PET was the least successful of the Trinity machines, with under 1 million sales. The Model I combined the motherboard and keyboard into one unit with a separate monitor and power supply.
The Model I used a Zilog Z80 processor clocked at 1. The expansion unit allowed for RAM expansion for a total of 48K. The expansion unit allowed up to four floppy drives to be connected, provided a slot for the RS option and a parallel port for printers.
The Model I could not meet FCC regulations on radio interference due to its plastic case and exterior cables.
Apple resolved the issue with an interior metallic foil but the solution would not work for Tandy with the Model I. Radio Shack had sold 1. Home computer Byte in January announced in an editorial that "the era of off-the-shelf personal computers has arrived".
The magazine stated that "a desirable contemporary personal computer has 64 K of memory, about K bytes of mass storage on line, any old competently designed computer architecture, upper and lowercase video terminal, printer, and high-level languages".
This led to an explosion of low-cost machines known as home computers that sold millions of units before the market imploded in a price war in the early s. Atari 8-bit family Atari was a well-known brand in the late s, both due to their hit arcade games like Pongas well as the hugely successful Atari VCS game console.
Realizing that the VCS would have a limited lifetime in the market before a technically advanced competitor came along, Atari decided they would be that competitor, and started work on a new console design that was much more advanced. While these designs were being developed, the Trinity machines hit the market with considerable fanfare.
Atari's management decided to change their work to a home computer system instead. Their knowledge of the home market through the VCS resulted in machines that were almost indestructible and just as easy to use as a games machine — simply plug in a cartridge and go.
The new machines were first introduced as the and inbut production problems meant widespread sales did not start until the next year. At the time, the machines offered what was then much higher performance than contemporary designs and a number of graphics and sound features that no other microcomputer could match.
They became very popular as a result, quickly eclipsing the Trinity machines in sales.
In spite of a promising start with aboutsold bythe looming price war left Atari in a bad position. They were unable to compete effectively with Commodore, and only about 2 million machines were produced by the end of their production run. It was incorporated in as Ablesdeal Ltd.
The company remained dormant untilwhen it was activated with the intention of continuing Sinclair's commercial work from his earlier company Sinclair Radionics; it adopted the name Sinclair Research in In the ZX Spectrum was released, later becoming Britain's best selling computer, competing aggressively against Commodore and British Amstrad.
At the height of its success, and largely inspired by the Japanese Fifth Generation Computer programme, the company established the "MetaLab" research centre at Milton Hall near Cambridgein order to pursue artificial intelligence, wafer-scale integration, formal verification and other advanced projects.
The combination of the failures of the Sinclair QL computer and the TV80 led to financial difficulties inand a year later Sinclair sold the rights to their computer products and brand name to Amstrad. Sinclair Research Ltd exists today as a one-man company, continuing to market Sir Clive Sinclair's newest inventions.

Two years later, Gates brokered the deal that would give Microsoft one of the most powerful revenue streams in the history of American business: an agreement to provide an operating system for a new personal computer, or PC, being developed by the International Business Machines Corporation.
