Odd...Icky wrote: 25 Sep 2018 21:53 One thing I have noticed is the screen flashes white every now and again - every 3 mins or so.
Yeah! "exxos re-mashed version" of it though :)Icky wrote: 25 Sep 2018 21:53 Another thought is that when we have finished and get a working STF you will have a modern legible schematic.
No I don't have pin 8 grounded - let me try thatexxos wrote: 25 Sep 2018 21:57 Do you have both gnds connected on the keyboard connector ? Phil mentioned the keyboard caused issues without pin 8 connected..
Well thats the funny thing I did get sound at one point when testing with the diagnostic cart - don't know when abouts but I definitely had sound.exxos wrote: 25 Sep 2018 22:11 As for the audio, we dont know if the new audio amp works ... probably idea is to try the diag-cart via serial and get the sound test running... check the audio out pins on the YM chip directly on scope and see if you see some activity there...
I'm checking the YM circuit in general and not found anything yet...
Sound was before GLUE DATALINE FIX. I will check with scope thoughIcky wrote: 25 Sep 2018 22:14 Back in the thread somewhere. Cant remember if it was post or pre the GLUE DATALINE FIX.
Even more oddities then.. datalines were definitely wrong... not good when a fix breaks something though :roll:
