Abstract A cost-efficient design for a CRT computer terminal is presented. The need for a master processor is eliminated by designing a CRT controller to initialize a slave processor. The slave processor accesses a random access memory (RAM) in which is stored instructions which the processor executes. Upon initialization of the computer terminal, the CRT controller reads instructions to be executed by the slave processor from a non-volatile read-only memory (ROM). The instructions are transferred from the CRT controller to the slave processor. The slave processor stores the instructions in the random access memory. Each instruction, at the proper time, may then retrieved and executed by the slave processor.
