Hi, you have three options, a memory expansion that connects to the same port of the accelerators, exists boards to expand memory and add a FPU, or a PCMCIA expansion card, if my memory don't fail, it can accept cards up to 6 mb, i have one for my A600 of 2 mb. Exist other ways, simulate fast memory for programs that need fast memory, these programs split chip memory to simulate 1 mb of chip and 1 mb of fast, take a look to this program:
