The Plus is of course at one end of the chain (it's the bus master), but it is not terminated internally. No compact mac is, by the way.
FWIW I don't think any 68k Macs or early 1-bus powermacs are.
The early PowerMacs are terminated internally. In fact, they have an auto-termination feature which turns termination off if there are external and internal drives on the SCSI bus and turns it on at the motherboard if there are no external drives or no internal drives connected.
The Apple Hardware Developer Note for the NuBus PMs mentioned that the AV Quadras have the same arrangement. I don't know about the earlier Quadras and 68030 machines. If it weren't so late/early, I'd check the relevant developer notes.
Okay, I checked the IIci's developer note, and it doesn't say. I suspect that one would need to go to "The Guide to the Macintosh Family Hardware" for that one and my copy is in one of two attics in an unidentified box....
