for 68 pin chains, the non terminated ones are perfect.

but if you are putting SCA drives on 50 pin cables. you will NEED the terminators because of termination of the high byte of the bus.

I do, also, have a 80 pin SCA to 50-pin narrow adapter without active termination which is not in use. Can you use a 50-pin terminated cable with these and he 80 pin SCA to 50-pin non-terminated adapter??

Or how about adapting the 50-pin narrow on the SCSI card to 68-pin, then using an 80pin SCA to 68-pin non-terminated adapter on the HDD, then use a terminated 68-pin cable?

If all the jumpers are off the Cheetah than it should be terminating itself. (The jumpers for terminator power and status should be on a small flat block on the bottom of the drive.)

You sure that applies to the LC as well?

You’re absolutely right, my bad! I had the wrong page pulled up in the Cheetah Manual (I was looking at the N series drives).

That’s what I get for posting before coffee in the morning!
