This Axlon RamPower 128 is an original memory card upgrade for Atari 800 computers with 32K 48K or 128K capacity. It uses bank switching to swap extra blocks of ram into the computer’s address space.

I am selling this in untested condition because I do not know how to use it and cannot find a whole lot of information on how to do so. I have plugged it into the second slot of my Atari 800, and have tried both positions of the switch on top, but have not gotten it to function for me. I have taken pictures of the card underneath the protective cover and it looks in pretty good condition. There are some factory Bodge wires present and one leg of one of the chips is lifted, which is also connected to a wire… and my guess is that is factory done as well.

This came from an Atari lot with many working components, so I would be surprised if this card needed more than a ram swap or two to get working, if it isn’t already in working condition.
