# Hardware Review: Quicksilva Hi-Res Graphics Controller

Review of the Quicksilva hi-res graphics board for the ZX81, providing 256×192 pixel resolution with 14 new BASIC commands. Requires at least 4K RAM. Uses the QS connector and motherboard. Drawback: hi-res and normal display modes cannot be combined. Standard ZX81 power supply insufficient.
