D card (the half-sized one that Sequential currently sells), then yes DMA will work at 8MB. I've never heard of a RamFAST rev. D card mucking up DMA with a Sirius. If you are using the new Turbo/Microdrive IDE card (the new one that can support 2GB drives, not the old one), then it will also DMA to 8MB. If you are using an Apple HS SCSI card, then DMA will likely fail at 8MB. Same with a RamFAST rev. C (the old CV Tech full sized model). >Also, what are the chances of the Sirius accepting standard PC parity >SIMMs? > >Daniel Ratzlaff (Norby) >norby@idir.net The chances? 100%. :) The card will accept 9-chip parity SIMMs or 8-chip non-parity SIMMs. The only 1MB SIMMs that it won't accept are 3-chip SIMMs. Having 8MB allows you to convert huge graphics files (TIFF, GIF, etc.) through Prism and digitize and play large sounds at high sampling rates. It will also allow you to load up a huge bank of system rsounds, since are memory resident. Although 8MB is not necessary to _run_ programs, it makes the computer generally more powerful for manipulating _data_ generated or handled by those programs. :) -Scott G.
