I don't know about Mac monitor cables but AUI
cables are not strictly straight
through. If I recall correctly, AUI cables are supposed to consist of four
individually screened pairs. The remaining 3 pins may or may not be connected.
It is 4 pairs, but I don't rememebr them being individually screened (and
I have made AUI cables). 3 signal pairs (transmit, receive, collision)
and a power pair. The powerpair is thicker wire than the other 3.
I doubt very much if Apple designed their monitor
cables to be compatible with
this - in the early Mac era anyway, I never knew them as wanting to be
compatible with anything, even equipment that it might be more reasonably
expected they should be compatibile with. Even (some, all?) Apple's AUI
cables are not compatible with standard AUI cables!
Apple had AAUI, which was aon a differnet conenctor and had 5V trasnceier
power, not 12V. I guess the last allowed them not to have a 12V power
rail, buit it was typical of Apple to be different.
AUI cables tend to mostly use clips to hold them in
place while other
applications tend to use screws and many AUI cables will need the clips to be
One reaosn I ahve to make my own AUI cables was that PERQs have screw
posts on the ethernet conencotrs. So I needed a cable with screws at the
male end and a slidelock at the femal end..
