Commodore Amiga 4000 hack to handle 64Mb of Fast Memory

The Amiga 4000 motherboard can be ´hacked´ to handle 64Mb of Fast Memory, to do this, you have to solder a new GAL and make some bridges between FASTRAM SIMM -> GAL -> CHIP RAMSEY.

This work is not complicated but you need to have a good practice with the soldering iron and PLCC soldering.
