Also, how long is that chain? I had problems when I had wide and narrow devices on a BusLogic 958 card 'cause my SCSI chain was something like 15 feet long. Also, removing that ZIP drive with its stupid 25pin SCSI made a big difference. I now run it on a 2842 (VL) with some other narrow external devices (and no internal devices), and it seems to work okay, but it works even better when it's on its own cheap ISA controller. Leonard Z had said several times that these "cheap 25pin SCSI interfaces" can wreak havoc on a "real SCSI" chain.
