PicoROM
PicoROM is an 8-bit ROM emulator in a DIP-32 and DIP-28 compatible form factors. PicoROM can emulate ROMs up to 2MBit (256Kbytes) in size and access times of 70ns. Its size allows it to fit into almost any ROM socket regardless of how crowded the board might be.
PicoROM is designed for prototyping and rapid iteration. A new image can be upload in less than a second over the USB connection using a simple command line tool. If you have ever found yourself in a situation where your iteration loop requires you to pull a ROM from its socket, erase it, flash it and put it back in for every code change, then you are who this was designed for.
The PicoROM comes fully assembled and flashed with the latest firmware version. The pins are Aries Electronics coined contact headers that are gentle on sockets and easy to install and remove.
