Seriously, & with all respect, Kick back a Chill about this.

Your Z3 SCSI II 50 way Ribbon cable will need terminating in accordance with the number & type of SCSI devices you have attatched to it. If you are going to confuse matters by adding SCSI III devices to SCSI II Controllers, you will need to terminate the SCSI III devices Upper/Lower 8 bit addresses through the Converters you attatch to the SCSI III Devices in order to get the SCSI II controller to talk to them with the correct Protocols, but ONLY when you have terminated the SCSI II Controller correctly. This can change depending on what type of SCSI devices you have on the BUS.

SCSI is a complex protocol to terminate properly. Normally, more than 1 SCSI device on ANY type of SCSI bus (1, 2 or 3),
then the SCSI standard says you have to terminate the LAST device in the SCSI chain with an Active terminator.
I have had a scenario with 2 SCSI drives and an Archive 250Mb SCSI Tape Streamer on the end of the Bus. If I put termination on the SCSI Bus (the cable), the tape streamer would NOT fucntion & that was on an Octogon SCSI card with RAM.

SCSI in the real world does NOT always conform to SCSI Standards & a guy I know as a Systems Manager on UNIX will confirm what I'm saying here.

Some of this stuff with SCSI is a "suck-it-and-see" scenario. Give Marcin chance to reply & see where you go from there!

Sir-German, are you conversant with SCSI Protocols & how to set SCSI configurations up?
