+
+In 1978 was born the **MK-14**, the first computer made by the Sinclair company (called at the time **Science of Cambridge** because Sinclair name was used by another company).
+
+The MK-14 was a training board sold in kit form costing around £40 and featuring a National Semiconductor SC/MP 8-bit processor, 256 bytes of RAM, 512 bytes of ROM holding a monitor, calculator keyboard and display, and some I/O ports.
+
+In fact, Clive Sinclair was not very enthusiastic about a personal computer project. The MK-14 project was thus managed by **Chris Curry** and produced by National Semiconductor. As the system was five times cheaper than its closest competitor, the Compukit UK-101, about 20,000 MK-14 boards were sold in the U.K.
+
+Chris Curry, who believed much more than Clive Sinclair in the future of such computers, left the company in 1978, founded **Acorn Computers** with Herman Hauser and built its fist computer kit, the **System 1**. A few months later, Sir Sinclair decided that computers were a good way to raise money and started a new project: a complete computer for less than £100.
+
+Meantime, the MK-14 grew into a modular system and several additional cards allowed to expand the system: cassette interface, text and graphics video module and Eprom programmer. 128 and 256 bytes RAM expansion modules could also be added up to a total of 640 bytes, Yes...640 BYTES...
+
+If the MK-14 had not been launched, Clive Sinclair wouldn't probably think so soon of its ZX-80 and the world personal computer scene would have been very different.
