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!
Dimensions: 2″ x 0.7″
- FLASH: 130048 bytes available
- RAM: 8192 bytes
- EEPROM: 4096 bytes
- IO: 46 pins
- ADC: 8 analog inputs (multiplexed to one ADC)
- PWM: 9 outputs
- UART, I2C and SPI hardware interfaces

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/
