Apple SCSI

Hi, I want to move my scanners over to one of these Macs (probably the 840AV since I can also exploit the video capabilities thereof). But, it's got those wacky DB25 SCSI connectors. :-/ I have DB25-Centronics cables. And, DB25-HD50 adapters. The scanners have a hodge-podge of *different* connectors (sheesh! talk about "standards"... :< ). I assume a good goal is to minimize *connections* wherever possible. So, instead of DB25-HD50 adapter to HD50 cable, use DB25-HD50 cable, if possible. But, I'm nervous about the DB25's and their roles in all this. Is this just a regular SCSI (narrow, SE) bus with a few less returns? Or, are there other consequences of this connector choice? E.g., how much grief can I expect going *through* the slide scanner with DB25 coming in and Centronics going out? Is this just effectively a "DB25-Centronics" adapter with a device tap in the middle? Thanks! --don
