Modifications for a communication interface board

The objectives of this report had three sections. First, it is to modify a communication interface board by using erasable programmable logic devices to replace around SSI and MSI logic. Second, it is to simulate selected portions of the schematics using Altera Maxplus 1990 and Maxplus 2 1991 CAD programs. Third, it is to replace a first input first output (FIFO) device as well as serial to parallel and parallel to serial converters with new FIFO's that have internal converters.
