Thanks. There aren't any single-ended mode settings or anything, and I don't think it's differential.
When I turn on the computer - either with the drive in the enclosure (I was using that because of possible termination issues although I don't know that the enclosure has termination; I just suspect it may) or in the machine - it powers on with the machine, starts to spin, then shuts down after what seems like a diagnostic cycle. That's regardless of the jumper settings. I had tried experimenting with combinations of those 3 (Target Init, Unit Attn, and Term Power) at the suggestion of Sonic Purity. I don't know if people here still know him.
Long story short, neither of us could figure it out so I assumed it was the adapter. When my 2gb 50pin died last week I started fiddling with it again and got another adapter [literally the only two different ones I could find on Amazon]. I'm open to suggestions about adapters but I increasingly have trouble believing that's it.
