Title: 044 board schematic needed
Post by: badlanding on October 03, 2018, 02:46:37 PM

Greetings!


I’m trying to isolate an audio problem, I have synthesized audio but very weak digitized audio (or maybe the other way around), the audio was fine with a 3902 board. So I’m guessing that the 044 board or the new backplane has an audio problem. Does anyone have schematics that I can borrow?


Thank you!

Thank you sir!  Could I persuade you to post page 14? Page 13 is shown twice and I suspect page 14 shows the main connector pin out. Thank you again.

I would if I had it.  I guess that must have been an error in the original document.


I posted the motherboard schematics.  I think it has the pinouts you're looking for.
