Perhaps a suggestion should be made to Titan to have a 32 bit SCSI card
developed for the AB. They deal with The Upgrade Shop (TUS) that makes
hardware. Perhaps that would be the best way then Ultra Wide SCSI could be
implemented or FireWire (which would be useful with having Apex used as a
movie file editor with the slew of new digital camcorders. From a software
driver aspect, there is Uwe and Sven that may have better ideas of getting the
bottlenecks out by making improved scsi drivers. What ever happened to Doug
Little? I never see any more messages from him.
