I've been having some success with my FWB card. I went to Weird Stuff and bought some active terminators. They have boxes of them for $1 each for all different kinds. Passive, active, external, internal, etc. I also terminated the onboard SCSI at both the external and internal. After doing that, I was able to get my IIci to boot without a Sad Mac. I then even got it to boot off a 5400 RPM 68 Pin SCSI drive without freezing! Also got a centronics active terminator for my peripherals. With an active terminator, I'm going to give those other jumpers a try.

Unfortunately my last 15K RPM drive died. They keep dying on my G4. I don't know why. If I ever run into some extra money, I think I'll just bite the bullet and get a SATA card and a relatively cheap SSD for my G4. SCSI on that thing has become too expensive with my failed drives.
