The Tecnowarp features four software selectable speeds (1.0MHz, 2.0MHz, 3.6MHz and 7.2MHz) and can use an external switch to toggle turbo mode off and on. It also boasts user upgradeable firmware and jumperless configuration via inbuilt menus. No dips or jumpers to set!
Performance-wise, the Tecnowarp appears to be comparable to the elusive Applied Engineering Transwarp II which also ran at 7MHz.
The Tecnowarp is priced at $250 USD each (PayPal and shipping fees not included), discounts for multiple board orders.
