Mac monitor cables, however, are straight through DA15, as are AUI cables. If you need spares of those, they're usually pretty easy to find. Alexandre, if you don't need official Apple cables, I could probably find more plugs/sockets/backshells from the place I got them from last time that I sent to you. - Dave

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. 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! Using non-Apple AUI cables as monitor cables might sort-of work if all the required pins are passed through and the screens are not interconnected but the impedances are likely to be all over the place which might cause ringing and other display problems, particularly if the cable is long. 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 removed before they can be repurposed. They also tend to be stiff and heavy which may place excessive strain on the connectors on the Mac or the monitor. Regards, Peter Coghlan.

Indeed; I was going to say that my assumption was that the reduced size was to allow them to fit the plug for the Quadra 700 in the same space as the floppy connector on the IIcx/IIci, but then the floppy connector (as discussed in this thread) is actually LARGER. Perhaps it was to prevent confusion with the DA15 monitor port? And also a side of vendor lock-in, to be fair. I've seen AUI connectors (male and female) with both screws and clips. It's always a bit of a crapshoot, in my experience. - Dave

For a 50 meter transceiver cable, this implies that the distribution impedance of the power supplied to the transceiver shall not exceed 4 Ohm paul

The Apple DuoDisk cable is DB25 to DB19. I used the following to make my own cable: http://support.apple.com/kb/TA37054?viewlocale=en_US On Thu, Aug 14, 2014 at 12:49 PM, Chris Osborn <fozztexx at fozztexx.com> wrote:
