Computer Market

The Sinclair range of computers were by far Sir Clive's most famous products, making him a household name and a multi-millionaire as well as securing him a knighthood. Their continuing popularity is shown by the huge range of emulators now available and the thriving market in second-hand Sinclair computers. Most are fairly or very common and can be picked up at cheap prices. The very earliest, the MK 14 and ZX80, are now rare and often command high resale prices.

Please note that items offered for sale through eBay are usually second-hand and sold without any guarantees of any sort. They may well be sold without packaging or instructions, and may not even work at all. If you have any queries about an item being auctioned, please contact the seller. Planet Sinclair cannot take any responsibility for your transactions on eBay. Always ensure that you know what you are buying!
