Sinclair ZX Spectrum 16k – Vintage Computer Tech


The Sinclair ZX Spectrum 16k is an 8-bit personal home computer released in the UK in 1982 by Sinclair Research. Known for its rubber keys and also its rainbow stripe logo.

Referred to during development as the ZX81 Colour and also the ZX82, it was launched as the ZX Spectrum by Sinclair to highlight the machine’s colour display, compared with the black and white display of its forerunner, the ZX81. The Spectrum was released as eight different models, ranging from the entry level with 16 KB RAM released in 1982 to the ZX Spectrum +3 with 128 KB RAM and also built in floppy disk drive in 1987;  together they sold over 5 million units worldwide.

Sinclair Research The Company

Sinclair Research Ltd is a British consumer electronics company founded by Clive Sinclair in Cambridge. It was originally incorporated in 1973 as Westminster Mail Order Ltd, renamed Sinclair Instrument Ltd, then Science of Cambridge Ltd, then Sinclair Computers Ltd, and finally Sinclair Research Ltd. It remained dormant until 1976, when it was activated with the intention of continuing Sinclair’s commercial work from his earlier company Sinclair Radionics, and adopted the name Sinclair Research in 1981.

In 1980, Clive Sinclair entered the home computer market with the ZX80 at that time the cheapest personal computer for sale in the UK. In 1982 the Sinclair ZX Spectrum 16k was released, becoming the UK’s best selling computer, and competing aggressively against the Commodore 64 and Amstrad.

How much is a Sinclair ZX Spectrum worth today ?

So in short not really that much too be honest !! So best keep hold for another few years.

After doing extensive research on a well known auction site. We have seen them go for as little as £50.00 including shipping up to about £200.00 for a mint version fully boxed. So unfortunately not super valuable YET !!!
