The Quadra Overdrive doesn't change the number of wait states at all. It runs the processor at 50 MHz when the bus is relinquished by the motherboard. Everything else runs at the same, standard 25 MHz.
And thats exactly what I meant. it has to insert wait states for the bus to catch up. some peripherals dont like excessive wait states. And you cant relinquish the bus unless there is RAM, and ROM, and CACHE onboard the accelerator. Then you need a DMA interface in order for that to even think about relinquishing a bus.
