Re: Ultrawarp...
No Problems with the HS-SCSI. The HS-SCSI had DMA disabled (of course) since no slotbased Apple II(e/+/c...) Accelerator allows DMA on other cards in the same system (the exception is of course the IIgs). It might have worked to a degree on the 4mhz ZIPChip though (unconfirmed).
----
I cannot get to the setup of the RamFast with the Ultrawarp enabled (even at 1Mhz). I deactivated the DMA without the Ultrawarp installed but no luck so far since the DMA-Setting seems to be reset if i reboot with the UW installed.

1 step: boot with RF only
2 step: disable DMA in RF menu (in#5)
3 step: shutdown+install UW
4 step: boot with UW at 16.667mhz and slot #5 set to 1mhz speed
5 step: try to boot #5 (in#5) -> lockup with shit on screen
6 step: coldreboot and "poke 49245,0" to set UW to 1Mhz
7 step: try to boot #5 (in#5) -> lockup with shit on screen
8 step: coldreboot and "poke 49243,0" to disable UW
9 step: normal operation with RF -> RF has set "DMA: enabled" by itself!
----
I have found no method to disable DMA by hardware (Rev.D RamFast) like a jumper or dip-switch before booting, since there is only the termination-power jumper.
----
The RF remembers its settings if the UW is not installed, even after several cold-reboots and longer periods of not being powered on.
----
The RF works flawlessly with an Accelerator II and a Transwarp.
