Multiple internal SCSI devices in a SE/30?

LOL! I never said to use the adapter the first time around, just offered the pic as a divergent thought about the process. That was my bad.

I think your problem is a flaky connection in the splice-n-shrink setup, not necessarily related to any kind of alternate ground line voodoo. That process gives me the heebiejeebies. PCB adaptation seems inherently more reliable to me, definitely more easily documented and then implemented. I've gotta put it on paper in a roadmap/electron plumbing diagram to check and recheck visually.

The ground lines are connected on the 50-pin side of that adapter, so it probably shouldn't matter where they're wired up on the SCA side?

Thanks for the info about the ground lines, then it is most likely a bad connection in my wiring. It makes sense, because the errors I get on my Mac are inconsistent - probably depending on how much I've wiggled the wires around!

Before I order the adapter, I might first have a go at soldering the 50-pin ribbon wires directly onto the pins on the Asante card - that way there is a solid, single connection - instead of the multiple connection points I have at the moment.

Also, I'm still using the Asante ADB adapter to get my 5v power - so I'll get my multimeter out to test the voltage.

Thanks.

I wouldn't advise messing up the pins on the NIC as the Header/IDC ribbon cable connection is robust and reliable. Soldering the wires directly into the SCA adapter card will be reliable and robust. Soldering IDC ribbon cable onto the headers or underneath will be neither.

If you feel you must to go that route, make your connections on the solder side of the NIC PCB so as not to make a mess of the header/IDC connector interface.

SCA adapter has been ordered  Coming from China - I will report back in 4-6 weeks!
