Computers have become progressively more complicated through 30 years of development and only the very early designs show true simplicity. As a starting point we shall take a hypothetical machine based very closely on the first computer built at th

The most obvious deficiency is the lack of multiply and divide functions, but there is also a need for ari

No program of this complexity would be written directly in octal, and the systematic approach described here is one way in which it might be derived. In fact the approach adopted might be used to produce any signif
