They're bullshitting you (probably because their margin on other SCSI cards like the Adaptec is much higher 8( ). We use the SC200 extensively, and have been _very_ happy with them; our particular preference is that they have onboard active termination, where cheaper NCR cards have passive termination. Also, you might want to point out to the moron in the shop that PCI interrupts are lettered (INTA, INTB, INTC, INTD), not numbered, and that INTA on one slot is _NOT_ connected to INTA on any other slot. > Jim Shankland -- ]] Mike Smith, Software Engineer msmith@atrad.adelaide.edu.au [[ ]] Genesis Software genesis@atrad.adelaide.edu.au [[ ]] High-speed data acquisition and (GSM mobile) 0411-222-496 [[ ]] realtime instrument control (ph/fax) +61-8-267-3039 [[ ]] Collector of old Unix hardware.
