Mirage Imager

An addon that enables you to freeze any program and store it to disc. Made by Mirage Microcomputers Ltd. The device was also available for the ZX Spectrum, this version was called the "Mirage Microdriver", and saved data on Sinclair's "Microdrive"; an external high-speed tape drive.

The tool can backup RAM contents (including CPU registers pushed in RAM), but, unlike Multiface II, it cannot backup read-only I/O ports like CRTC (vram address/size) and Gate Array (screen colors) - the include software allows to manipulate that values manually.
