But we tried it, and it worked. Sounds like the scanner is internally terminated. That is bad. Also, most Seagate drives come internally terminated-- three to four terminators is also bad. I guess I'm blessed-- I've connected my system with from anywhere from 1 (mac only) to 3 (Mac, Imprimis, external) SCSI terminators, and EVERY CONFIGURATION has worked. Wanna trade my Mac II for your IIfx :-). -- Matthew T. Russotto russotto@eng.umd.edu russotto@wam.umd.edu .sig under construction, like the rest of this campus.
