YES! I got it to work finally with my Turbo 601. I found a website with "Turbo 601 eccentricities" with a cool copy of a FAX conversation between an owner of a Turbo 601 & FWB Card. Turns out I had to have the SCSI Manager 4.3 enabled on the 601 card. Mine was disabled for some reason. After I flipped it on, my computer booted!

I now have a Mac IIci with a Turbo 601 upgrade and Jackhammer SCSI card. Phew, that thing is finicky. I should print out the configuration and stick it with my manuals so I don't have to go through this again. :approve:

Gonna try out my other terminator resistors, see if they'll work.
