The Razer Tarantula™ Gaming Keyboard is the first definitive keyboard created For Gamers, By Gamers™. A cutting-edge companion to Razer's suite of gaming peripherals, it is specially engineered to empower competitive gamers with seamless control and unparalleled flexibility. Anti-Ghosting Capability With the anti-ghosting capability of the Razer Tarantula™, you can press up to an unprecedented 10 buttons at one go without the "ghosting" effect (For a conventional keyboard, signal failure occurs when three to four keys are pressed simultaneously). This means more commands can now be executed at any one time. Onboard Profile Memory With a 32KB onboard memory – Powered by Razer Synapse™ - up to five onboard profiles for different games can be stored. So no matter which LAN party you go to, all you need to do is bring your Razer Tarantula™ along, and you're ready to play. A Keytop That is Eight Times as Responsive The Razer Tarantula™ is the only gaming keyboard on the market with 1000Hz Ultrapolling™. This means a delay of only 1ms between the keystroke and the key's reaction, as compared to that of 125Hz / 8ms found in conventional keyboards. * Anti-ghosting capability for up to 10 keys * 32KB Razer Synapse™ onboard memory * On-The-Fly Sensitivity™ profile switching * 10 programmable gaming hotkeys * 1000Hz Ultrapolling™ / 1ms response time * Hyperesponse™ gaming keytop with fully interchangeable keys * Headphone-out and microphone-in jacks * Media center keys * Two USB ports * Gold-plated USB connector * Razer Battledock™ for add-on accessories * Approximate size: 522mm (length) x 220mm (width) x 33mm (height) System Requirements Windows 2000 / XP / X64 / MCE 2005 / Windows Vista 2 Available USB Ports CD ROM Drive (for drivers) At least 35MB of Hard Disk Space (for drivers)
