TPR is likely "Termination Power" the device will empower the bus in case voltage is weak.

This does NOT mean the bus is terminated. Termination has to be done seperately on the 50pin flat cable.

If you want to use ID0, no jumpers for SCSI ID have to be set.

If you need software for initializing your third party drive, you might try Lido:

Let us know how it goes, many of us will have to aquire old SCA server drives, as SCSI-1 50pin drives are becoming rare.

Edit: oops, just realized ojfd made things clear already.
