Introduction
Jeffrey W. Porter is an accomplished inventor based in Austin, TX, known for his contributions to microprocessor-based systems. With a total of 2 patents, he has made significant strides in the field of technology, particularly in program development and printer communication.
Latest Patents
One of his latest patents is titled "System and method for ROM program development." This invention discloses a circuit that assists programmers in developing programs to be loaded into read-only memories within microprocessor-based systems. The circuit acts as a ROM emulator powered by the target computer system, eliminating the need for an external power supply. It allows for reprogramming by the target computer system, even if the system is not designed for write cycles to read-only memory. The software developed is stored in an electrically erasable programmable read-only memory and can be reprogrammed from either the target computer system or through the parallel interface of a host computer system.
Another notable patent is "Computer with electrically isolated printer port using shunt transistors." This invention features a parallel port adapter that provides a special buffering circuit on the four control lines from the system to the printer. The circuit creates a low-impedance bidirectional path for communication between the CPU and the printer whenever any of the control lines is active. It employs blocking diodes on all four lines and uses pass transistors in parallel with the blocking diodes, utilizing power-robbing to activate the pass transistors whenever the port is in use.
