AMOS, a Ferranti Mark I computer, was a typical computer of the time with two-level storage (i.e. a working store using cathode ray tube technology and a backing store using a magnetic drum) with an interchange of data time for backing store to working store of 47 milliseconds while the reverse operation took 93 milliseconds (Berry, 1959) . For large problems this computer was efficient but, for smaller problems, an alternative system of programming was devised that was based on Brooker's Mark I autocode but unlike the autocode developed later by Brooker (as mentioned above). The AMOS Intercode was not intended to replace machine instruction (Berry, 1959); indeed, it retained many of the features of the instruction code.

An outline is given of a new scheme for preventing problems to the high-speed digital computer AMOS.
