How does a computer work without a processor?
The central processor is implemented by a set of TTL chips. They act as an arithmetic-logical device and control logic. All signals are synchronized at a clock frequency of 6.25 MHz. Programs are stored in ROM and executed by the interpreter. You get a complete understanding of the operation of each logic element.
