Supports 2716 -27512 sized EPROM Emulation. Battery memory
backup. Make transparent changes to Rom image while CPU is running.
Very popular with EFI hackers. The Romulator allows car folks to make
changes while-the-engine-is-running! No need to stop and start the
used for Microprocessor developers. Auto EFI/ECU folks new at this
