Predecessor was the Sinclair Spectrum. A successors was e.g. Spectrum Plus (improved keybaord) and the Spectrum 128 (128 kB RAM, 3-channel audio chip AY-3-8912, MIDI, RS-232, RGB monitor connection and improved BASIC). After Sinclair was taken over by the company Amstrad, the models Spectrum +2/+2A and Spectrum +3 with either cassette or 3" floppy disk drive built-in were launched.
Thanks to the rainbow colors and the black color, the flat case looks more modern than other computers of the time. The slightly too high rubber buttons feel spongy without a good pressure point. Due to the cost savings, the computer also lacks a power LED that indicates when the device is in operation.
At the back are few connections. A TV modulator that delivers a lousy picture is the only way to output a video signal. The sound is played by the internal speaker and not transmitted to the TV. Two jack plugs for headphones and microphone are used to connect a cassette drive as a mass storage device. The required cables were included. An external 9V power supply and a large expansion port complete the connection options. The latter is also urgently necessary because the Spectrum does not even have joystick ports by default.
At the back is the speaker on the bottom left. Embossed in the plastic is the model name, the memory expansion (16 or 48 kB) can be seen on a sticker. In addition, there are warranty seals that will void the manufacturer's warranty if the computer was opened by unauthorized persons.
The modern packaging of the Sinclair ZX Spectrum.
The back of the box shows what is included. It included a power adapter, two cables for the tape recorder, a TV connection cable, a BASIC manual, an introductory booklet and a demonstration cassette.
The power-on message of the Sinclair ZX Spectrum. You could not type commands letter by letter as usual with other computers, but each key was assigned to several commands so you don't have to type them in. On the keyboard of the Spectrum +2, however, most commands are no longer printed to the keys, which makes operation difficult.
