We've finalizing our tweaks, and are now ready to sell these screaming arrays. These are exciting times for hardware geeks, boys and girls. In the meantime, if you need to add narrow SCSI support to a Yosemite, Yikes, or Sawtooth, the Gurus unreservedly endorse the Initio Miles Bluenote. If Bluenote doesn't work with your scanner, you know who to blame, and it's not Initio. Again, consult the Initio website for firmware updates, as well as the website of your scanner manufacturer.
Good companies support their products, and release bug fixes frequently.
As for USB-SCSI adapters, we have noted that most simply don't work that well. We have found one that works most of the time, and will soon be offering it for sale on this site. If you are in the market for affordable speed, and require a shreddin' LVD SCSI subsystem that actually works as advertised, we strongly endorse the Initio Miles2 . It includes everything you require to get up and running quickly, for much less than you might expect. Yes, you can use this phenomenal board on a 32-bit vintage Power Macintosh.
