Abstract
Disclosed is a circuit for assisting programmers in developing programs to be loaded into read-only memories within microprocessor-based systems. The circuit acts as a ROM emulator and is powered by the target computer system, thus removing the need for an external power supply. The circuit may be reprogrammed by the target computer system even if the target computer system is not designed to allow write cycles to read-only memory. The software to be developed is stored in an electrically erasable programmable read-only memory, and may be reprogrammed either from the target computer system or through the parallel interface of a host computer system.
