I have an B2000 with an A2620 accelerator board. I also have a Supra WordSync SCSI Interface, which I'm about to install. The software is "Series II, ver 1.09f". In a minor note on page 16 in the manual, I read: "If you install a 68020, 68030 or 68040 accelerator board in your Amiga 2000, you need to use the SupraEdit program to mask out DMA to 32-bit RAM. A mask value of 0 will allow things to work safely, although not necessarily as fast as possible. To determine the optimum mask value for your system, experiment and/or contact the manufacturer of your accelerator board." Commodore Sweden don't know what an A2620 is, so I can`t ask them. I don`t really understand the connection/problem with DMA to 32-bit RAM and the Supra non-DMA SCSI interface. Anyone with a good explanation? What mask value could I safely use? (I don't feel like trying all values from 0 to FFFFFF). It's also interesting to know if the software has undergone any major revisions? What is the current revision? Anyone have the Fax # to Supra? Thanks in advance, Tommy Petersson
