Well, before I explain what an EPROM Emulator is, I should first explain what an EPROM is. EPROM or Erasable Programmable Read-Only Memory is a type of programmable read-only memory that is used to store program in “computers”. And when I say “computers” I refer to the 80s eight bit machines (Commodore, Amiga ZX Spectrum, Tandy etc.), but also other computer like devices, controllers etc. that require program memory. Those EPROMS typically come as ICs in DIP28 package with a “window” in the middle used to “erase” the memory using UV light.
