From the project

4 MB Fast RAM Expansion for the Commodore Amiga 600

OpenAmiga600FastRamExpansion will allow you to add 4 MB of Fast RAM to your Amiga 600. This way you will be able to run more applications at once and more quickly. If you combine it with a chip RAM expansion, you will also be able to run almost all games supported by WHDLoad, pushing the smallest of the Amigas to its limits. The Fast RAM will be mapped to $200000-$5fffff, which means it will not interfere with the PCMCIA address space.
