The Senior PROM is a debugging and copy protection removal aid for the Apple //e. It consists of a circuit board with replacement firmware EPROM and a button that triggers an NMI (Non Maskable Interrupt), along with a disk containing utilities. Amongst other features, the Senior PROM can allow an running program to be written to a 'resurrection disk' which when booted resumes the program. This allows for creating backups of 'single load' games.
