The lead would need to be from a New Motherboard desk as there was apparently a possible manufacturing fault with a number of the plugs used in the quite early Old Motherboard desks. Apparently it was the luck of the draw at the time if you got a desk with good or bad plugs, or a combination of both, because when the later batch of now suspected faulty plugs were discovered it was found that when the suspect batch arrived they were simply tipped into the box containing the good plugs --- hence the luck of the draw as to what plugs were used on (say) your desk !!!!!
If I remove the cable and quite bruitally attack the cables with (say) a small screwdriver where they go into the top of the plug then re-attach the two plugs to the two boards, the desk works perfectly for some time, but then faults again --- no audio and meter freeze and this is what was discovered back in 2006 with the fault being put down to those two plugs.
I have tried to purchase new plugs to make a new cable, but I am not able to find a supplier/retailer of 5 pin Molex plugs (4, 6, 8 pin yes but 5 pin no !!!) --- at least I think that they are Molex plugs. I even purchased a couple of 6pin plugs and wired those (leaving what would be the bottom female slot vacant) but the female holes on the plugs purchased were just a fraction wider apart and as such they would not fit onto the male pin section.
If anyone does have a suitable J42 lead let me know how much you want for it (will be sent/mailed to Queensland, Australia).

Look up the part in the available BOM documents, cross-reference it on [
Mouser, Digikey, etal] and order the connector. It's an IEEE standard Molex connector type, it's not something that Mackie '
made' or had tooled for them. It's production-based stock...
Again, if it were me, there isn't any way I'd be soldering wires directly to birdpost connectors on any piece of gear, let alone a mercurial D8B. Under the best of circumstances, it's gonna be nothing less than janky...
And of course, you surely knew this was coming... so here it is :
