The Elliott 503 was a
transistorized computer introduced by
Elliott Brothers in 1963. It was software-compatible with the earlier
Elliott 803
The Elliott 803 is a small, medium-speed transistor digital computer which was manufactured by the British company Elliott Brothers in the 1960s. About 211 were built.
History
The 800 series began with the 801, a one-off test machine built in ...
but was about 70 times faster and a more powerful machine. About 32 units were sold.
The basic configuration had 8192 words of 39 bits each for main memory, and operated at a system clock speed of 6.7
