Calling it with SE/30 Simasimac Board

This might just be the default state of the VRAM. I replaced one of the 41264s with a Texas Instruments version

Oh wow.... what a way to end the weekend. Pin 5 of UE7 to pin A6 of the CPU. Still don't have sound, but a major win for now. Thank you to everyone for the help...

Applause! Congratulations on getting the video working! Persistence pays off, finally.

Did you recap the board? Problems with the sound are most often solved after a recap.

@bigmessowires Yes, finally. Super happy about it, thanks!
@dochilli Yeah it was recapped a while ago. Through all of this simasimac troubleshooting and testing, I wonder if I fried the speaker. I also did replace chip UA9 in the process. It always had been working, though with crackling. Now its just the crackling.. it'll be a problem for next weekend though haha
