ColecoVision 31-in-1 Flash Cartridge
Version : 24/03/2013 - FIX 3

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.

ColecoVision 31-in-1 SMD Mini

Version : 28-02-2013 - Not tested yet.

This board is made to store 31 rom files into a single UVPROM (1M x 8 bits).
This one is the same as the previous ColecoVision 31-in-1 SMD but smaller. The goal was to make a specific version to be made by a sub-contractor.

Enjoy !

ColecoVision 63-in-1 SMD

Version : 28/01/2013

This board is made to store 63 rom files into a 2 UVPROM (2 x 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 63 images), switches to the corresponding memory bank and launches the image.

ColecoVision single ROM Cartridge

ColecoVision single ROM Cartridge, déc. 2012


ColecoVision single ROM Cartridge


This board is made to be used with one ColecoVision ROM file (up to 16Ko).
For the moment, only one file can be stored to the EProm (no bank switching or bank selection).

This PCB corresponds to the remake of my previous version (24/10/2008).


Files
Coleco-Rom-Cart.sch : Schematics (Eagle 5.0.0)
Coleco-Rom-Cart.brd : PCB (Eagle 5.0.0)

Usage
Just 'flash' one 2Ko, 4Ko, 8K or 16Ko files to the UVProm and plug-in the cartridge into the console.


Enjoy !
