What this diagram shows is that there is a barrier between the programmer
and the central proccessing unit of the computer. It is not possible
under normal programming for the progra~ner to tell the central processing
unit - usually referred to as the CPU - what to do.
In the Sinclair machines the CPU is a Z~A chip??? and [ am sure it comes as
no surprise to learn that the ZSOA does not understand a word of \"BASIC I
Indeed no CPU is able to be programmed in a way that is directly readable
by humns.
