The V4 is designed to replace the V2 V500 model as an accelerator, as well as operate entirely independently of any computer in a so-called "standalone mode". To accomplish this, Apollo Accelerators has built a cleanroom version of the AGA chipset and added direct support classic DB9-based joysticks and various low or full-speed USB 2.0 peripherals such as mice, keyboard and gamepads. Amiga AGA graphics are automatically upscaled to HDMI (576p) resolution and can switch automatically between classic and SAGA display modes for use with modern LCD monitors and televisions.
