Re: fx termination
Sounds like an active terminator, which should work better than the Special Black IIfx one. Termination power must be provided to the bus, either by the host adaptor (Mac) or one of the drives to use an active terminator. Its generally not a good idea to have more than two devices providing termination power to the bus. Set one device to provide power to the bus and the rest to provide termination power only to themselves or disable it on them. --- Desert Fox [EMAIL PROTECTED] wrote: My Mac IIfx terminator is black with no green light. -- Paul/. 95 black 3000GT VR-4 98 VFR800F, TBR aluminum hi exit formerly reasonable and prudent on 7/25/01 10:15, Scott Barber at [EMAIL PROTECTED] scribbled: I tried to post this question the other day, but it hasn't appeared on the last two digests, here it is again: Does the black terminator used for external SCSI devices with the MacIIfx have a green led?

IMHO the special fx terminator isn't needed for short distances. SCSI is specified to work over a long distance that most of us never encounter. Longer distances require more ideal termination (i.e. impedance matching). My fx has always worked fine with standard external SCSI termination at lengths up to 4 feet, and I bet it would go up to at least 10 feet with no problem.

Gamba http://www.accesscom.com/~gamba There is an article somewhere at apple.com which tells which IIfx models need the special terminators. IIfx shipped prior to (some date) need the special external terminator and an internal SCSI filter or internal special terminator if not using an internal drive. (Who would ever have ordered, let alone used, a IIfx without an internal HD?) IIfx shipped after that date do not require any of the special terminators or filters. Apparently at some point Apple fixed the problem. Unfortunately they didn't put any easily identifiable marking on the logic boards or anywhere else to tell which are the revised ones. :P Someone had a website with a Mac serial number decoder so you could tell when your Mac was built, but Apple threw a fit and threatened to engage in lawyer tossing over it. The first power up date in PRAM is not a sure fire indicator of how old the Mac is. If you leave the PRAM battery out or dead long enough the PRAM will totally erase and lose that setting. = The earth swarms with inhabitants.
