Retrieve data from EPROMs with Arduino

 For one reason or another you may have the need to retrieve the data stored in an old EPROM (erasable programmable read-only memory) IC. You may be trying to reverse-engineer some vintage technology, curious about the character set in a display driver or just looking for a new challenge. Nevertheless, using an Arduino Mega-compatible board and some simple instructions from the NYC Resistor hackerspace - dumping the EPROM contents can be quite simple.

For a fascinating read and more information, visit the NYC Resistor website. To get started with your own EPROM-dumping a board such as our Freetronics EtherMega is perfect. It has the extra I/O pins and is fully compatible with the Mega2560, and also has onboard Ethernet, microSD socket and optional power-over-Ethernet support:
