KDF8 was an early British computer built by English Electric as a version of the RCA 501. By producing a software-compatible system, the intention was to reduce time and cost to develop software. However, the lengthy process of developing manufacturing capability meant that the system was soon outpaced by systems from other vendors. Only a few systems were sold during its 5 years of production. Due to the consolidation of the British computer industry, English Electric's computer division became one of the components of what would become ICL.
