SCSI devices usually have three options for TERMPWR. They can provide it to the bus, to themselves or to both. It doesn't do anything to have the device provide its own TERMPWR if it isn't the last device at one end of the chain. Some devices use one jumper to both provide their own TERMPWR and enable the onboard terminator. The easiest way to configure all your SCSI devices is set them all with termination disabled. Then set one internal and one external device that you'll always have connected provide TERMPWR to the bus, and enable the termination on the internal hard drive with ID #0 which will be at the end of the chain and always in use. That way it won't matter how your external SCSI chain is configured as long as nothing has the same ID# and you always plug an external terminator into one port on the last external device. What I've done many times, and it's always worked, is to connect my external Zip 100 as the last device and enable its built in terminator. The problem is the Zip can only be set to ID# 5 or 6. :P Same for the internal SCSI Zip 100 in my PC, which is the early model permananetly mounted in a 5.25" frame with a blue faceplate. But it's very well built! It survived a "death disk" with a ripped edge that had beheaded a couple of 3.5" internal Zip 100 drives. :) It went *THUNK* *THUNK* and I just yanked out the power cord on the computer then used the emergency eject hole on the Zip drive. ===== "Work it harder make it better do it faster makes us stronger.
