The ZX Spectrum is remembered for its rubber keyboard, small compact size and distinctive rainbow motif. It was originally released in 1982 with 16 KB of RAM for £125 and later reduced to £99. Owners of the 16 KB model could purchase an internal 32 KB RAM upgrade.
Later issue machines required the fitting of 8 dynamic RAM chips and a few TTL chips. Users were able mail their 16K Spectrums to Sinclair to be upgraded to 48 KB versions. To reduce the price, the 32 KB extension used eight faulty 64 kilobit chips with only one half of their capacity working and/or available. External 32 KB RAM packs that mounted in the rear expansion slot were also available from third parties. The ZX Spectrum also had 16 KB of onboard ROM.
Our 16K Spectrum has blue-grey keys and a serial number of 002-679375.
