Abstract: A Universal Memory Loader Verifier (UMLV) is disclosed. The loader comprises a system used to load and verify Operational Flight Programs (OFP) into an unlimited number of different types of avionics computers without the need for adding additional hardware (with the exception of an additional cable that may be unique to each particular computer being loaded and verified). The disclosed Universal Memory Loader Verifier (UMLV) consists of a portable, off the shelf, militarized, arm held, battery backed Personal Computer. The PC contains a custom interface card for different types of applications. The PC output is connected to a buffer box having a custom card therein by means of a cable. The buffer box is connected to a single ended driver/receiver type avionics computer through a unique cable. This connection requires an additional cable for each computer type. For all other applications, the PC is connected directly to the avionics computer by means of a unique cable.
