MK14
Also known as MK 14
The MK14 (Microcomputer Kit 14) was a computer kit sold by Science of Cambridge of the United Kingdom, first introduced in 1977 for £39.95. The price was very low for a complete computer system at the time, and Science of Cambridge eventually sold over fifteen thousand kits.

The design was unusual in that it used the National Semiconductor SC/MP microprocessor, which was not widely used in this role. The original design was custom, based on a Sinclair calculator as the main input and output device. National Semiconductor offered them the design of National's IntroKit single board computers for free if they agreed to a purchase agreement on the parts, which would be lower than what they could negotiate separately. The original design was dropped in favour of National's offer.
