The 7870 is "a SCSI Controller on a chip". It only needs external logic to wire up a BIOS, differential drivers if you want diff scsi, and an optional SEEPROM for configuration info. It would be very hard to make a controller with a 7870 on it that we didn't support. > >> Paul > >-- >]] Mike Smith, Software Engineer msmith@atrad.adelaide.edu.au [[ >]] Genesis Software genesis@atrad.adelaide.edu.au [[ >]] High-speed data acquisition and (GSM mobile) 041-122-496 [[ >]] realtime instrument control (ph/fax) +61-8-267-3039 [[ >]] "Who does BSD?"
