Who developed the earliest stored-program computers, that was funded and purchased from Ferranti in the UK instead?
Manchester Mark 1 The Manchester Mark 1 was one of the earliest stored-program computers, developed at the Victoria University of Manchester from the Small-Scale Experimental Machine (SSEM) or "Baby" (operational in June 1948). It was also called the Manchester Automatic Digital Machine, or MADM. Work began in August 1948, and the first version was operational by April 1949; a program written to search for Mersenne primes ran error-free for nine hours on the night of 16/17 June 1949.
DEC T-11 The T-11, also known as DC310, is a microprocessor that implements the PDP-11 instruction set architecture (ISA) developed by Digital Equipment Corporation. The T-11 was code-named "Tiny". It was developed for embedded systems and was the first single-chip microprocessor developed by DEC. It was sold openly and was used by DEC in disk controllers, auxiliary processors and in the Atari System 2 arcade game system. It operated at 2.5 MHz, used a 5 V power supply and dissipated less than 1.2 W. It contains 13,000 transistors, uses NMOS logic, and was fabricated in a NMOS process.
