Since the RamFast has its own Processor and Ram, it could scan the bus and set itself up to match the systems requirements. The Transwarp (even the TWII), the Accelerator II(e), the ZIP- and the RocketChip,... had all been well known when the RamFast (revD) came. Since other (non-DMA) Cards work with a Ultrawarp equipped system like they should, the DMA of the RF might be the problem. BUT it could be something entirely different as well. I don't know enough of the Apple-2's subsystem and even less about the Ultrawarp's internal structure to pinpoint the error which is causing the 'hiccups' when accessing the RF.

Did you disable DMA on the Apple II High Speed SCSI card?  You listed it as fully compatible with the Ultrawarp.  Was DIP switch one on or off (closed or open)?
