Dumping an EPROM using an ATMEGA MCU

I recently built a development board using an ATMEGA 1284-PU microcontroller and some spare components I had lying around. Since then, I searched for fun & cool things to do with it: there are the usual sensors reading/LED matrix lighting/graphic LCD drawing/motor controlling experiments available, but my interest lies in data preservation so, as a first task, I decided dump a few EPROMs that dwelt undisturbed in my junk box for too long.

This mess of wires actually works as an EPROM dumper!
