This is the A2000 version of the Action Replay Mk-III. The device plugs into the CPU slot, not a Zorro slot which means if your accelerator uses the CPU slot, you won't be able to use this device. The device allows the user to freeze the computer at any point they choose where upon a new display opens that allows the user to view memory contents, rip music and graphics or cheat in games. It also had the option of saving memory to a bootable floppy disk which when loaded would place the memory in the exact state when the machine was frozen. This allows the user to copy games by bypassing the copy protection.
