Colecovision-Cms-Pcb.png ColecoVision 31-in-1 SMD
Version : 19/01/2013
This version corresponds to the ColecoVision 31-in-1 Flash Cartridge - 14/01/2013 - FIX 2 with SMD components.

This board is made to store 31 rom files into a single Flash or UVPROM (1M x 8 bits).
To use it, you need a specific 'bootloader' stored at the bank 0 location (first 32k bytes).
All other rom images must be stored into the other 32K bytes banks.

Running the bootloader lets you choose a rom image (between 31 images), switches to the corresponding memory bank and launches the image.
