Scandoubler specifically designed for use with the Cybersion 64/3D from Phase 5. Whilst it can be used with the gfx card, it is primarily designed as a means for displaying Amiga native screen modes and graphics card modes on the same monitor. Supports both PAL and NTSC. Connects to the gfx card by a small ribbon cable. This card can only be used in AGA type video slots.
