The new hardware had compatibility issues with old software and peripherals. The Spectrum 128 suffered from being released after the holiday season to an uninterested public.

The English Spectrum 128 did not include an external keypad and the keypad port was renamed 'AUX.' The keypad was released separately for ВЈ19.95 and did not sell well. It was unveiled and launched in Spain in 1985 for 44,250 pesatas the English release was pushed back until 1986 because of unsold Spectrum inventory and retailed for ВЈ179.95. It was developed by Sinclair in conjunction with their spanish distributer Investronica. The Spectrum 128 also fixed the 'dot crawl' problem that earlier units suffered from.

The Spectrum 128 was an evolution of the ZX Spectrum lineup, sporting 128K RAM, 3 channel audio, MIDI compatibility, a serial port, RGB video out, 32Kb ROM, an improved BASIC editor, and an external keypad. The plastic keys on the Spectrum had a tendency to fall off, and retailers expressed failure rates ranging from 5% to as high as 30%. The price was cut to ВЈ129.95 with the release of the Spectrum 128.

The ZX Spectrum+ retailed for ВЈ179.95 and a do-it-yourself upgrade kit was released for ВЈ50, which allowed a user to upgrade any rubber-keyed Spectrum with plastic keys. The keys still rested on a rubber membrane and while it improved upon the original design, many users did not find it completely satisfactory. The most important change with the Spectrum+ was the introduction of a 'professional keyboard' which had injection-molded plastic keys rather than rubber ones. The ZX Spectrum+ was a 48K Spectrum in a Sinclair-QL style case (another computer launched in 1984). In 1984, two years after the release of the original Spectrum, Sinclair released the upgraded ZX Spectrum+. The 48K model is virtually the same as the 16K model, with the obvious exception being the upgraded RAM. The 48K model launched alongside the 16K model in 1982 and retailed for ВЈ175. This caused a problem called attribute clash (also known as color clash) which required creative graphic design to circumvent. The downside to the Spectrum's color was that only two colors could be in a single 8x8px square. The 256x192 resolution of the computer was above average for its time, and the choice of 8 colors (15 including 'BRIGHT' colors) set it apart from the competition. The rubber keys are mushy, and the fact that keys can have up to 6 functions each means that even typing basic commands requires extensive use of the function keys. The keyboard of the computer is considered to be terrible for typists. Third parties released 32K RAM expansion packs that plugged into the expansion port as well. An interesting note is that to save money on these RAM expansions, Sinclair used defective 64K chips with only 32K RAm actually working or available. Users could mail in their systems and they'd have their Spectrums fitted with a 32K daughterboard that made it essentially identical to the 48K model. A 32K RAM upgrade was available for 16K users to upgrade their systems to 48K. The 16K model launched at ВЈ125 and later dropped to ВЈ99. The original ZX Spectrum is very widely recognized for its signature rubber keyboard and rainbow flair in the corner of the device. It launched alongside the 48K model and was very similar except for the memory difference. The 16K model was the entry level model manufactured by Sinclair in 1982.

There were eight models of the Spectrum produced between 19, and the recognizable computer spawned a good deal of clones and imitators. It was a well supported platform with a variety of companies developing software for it, including many games. The popularity of the Spectrum in Europe can be compared to that of the Commodore 64 in North America as it was made to be the cheapest available color computer at the time. The ZX Spectrum was particularly successful in the UK, and was one of the most popular personal computer throughout Europe in the 1980s. Affectionately regarded as the 'Speccy,' the Spectrum was Sinclair's first computer capable of color output, and is widely recognized for its complex 40-key rubber keyboard. The Sinclair ZX Spectrum was the successor to the ZX 81 released in the UK by Sinclair Research Ltd.
