Nice work @PaulJ! There go my dreams of competition glory. :lol:

Now that you have a working system, could you do me a favour and check the resistances between video DAC pins 7 and 8, 31 and 32, and 43 and 44 (i.e. three pairs)? I suspect something is up with mine there and would like to compare. Thanks!

EDIT: Oh yeah, and can you tell me how hot your DAC is getting? Mine's hot, right around pain threshold. Wondering if that's normal.

Sure, but Paul got his on 27 November and I got mine on 21 November, so I am officially out. :D

Could still qualify for the booby prize though. :mrgreen:

Nah, no chance...just wait until I get my bare board (as well as the built-up one) - it'll probably take me until Christmas 2020 to get that one built & working. :lol: :roll:

Yes, I'll check the resistance for you. My DAC also gets pretty warm, as you said you can leave a finger on it but you notice its warm.
