My project with Adam Mayer at NYC Resistor to read every PROM that we find continues into its fourth version. The latest is most compact and flexible yet — the entire design piggybacks a pjrc Teensy++ on the 40 pin DIP ZIF socket from Adafruit Industries with almost no wiring and is super flexible. It can reroute the pins in software, so most any five volt DIP ROM, EPROM or EEPROM can be read.
Teensy++ (AT90USB1286 USB dev board) + header! The Teensy++ is a complete USB-based microcontoller development system, in a very small footprint! All programming is done via the USB port. No special programmer is needed, only a standard “Mini-B” USB cable and a PC or Macintosh with a USB port. Its the big sister version of the popular Teensy board we carry, this board has tons of FLASH, RAM, pins and more. This is the latest version, 2.0.
Key Features:
USB can be any type of device
AVR processor, 16 MHz
Single pushbutton programming
Easy to use Teensy Loader application
Free software development tools
Works with Mac OS X, Linux & Windows
Tiny size, perfect for many projects
Comes with headers pins that you can solder on to plug it into any solderless breadboard
Comes with assembled Teensy++ board (AT90USB1286 with bootloader preinstalled) and header to allow easy breadboarding. We suggest using AVR-gcc (like WinAVR) with the LUFA library or ‘Teensyduino’ Be sure to check out the multiple resources available at PJRC!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

One of the first ROMs that we dumped with the PROMdate had a great Muybridge-esque animation of a galloping horse: http://www.flickr.com/photos/osr/7736763006/
