Re: Super Game Modul

Ooh exciting!
I'm just hoping you have better luck than me with PCB design. One of these days I'll have a PCB work first go :-D

Re: Does anyone have an early revision CreatiVision they can photograph the PCB for me?

OK, I'm back. Been on a week long cruise to see a total eclipse.
(Totally worth it)

Re: Does anyone have an early revision CreatiVision they can photograph the PCB for me?

No that's perfect! I think I can see what's going on with mine now. And that photo from the bottom shows the second inductor that I couldn't find on mine. Brilliant. (My current issue is the clock circuit isn't going into resonance, so the TMS isn't getting a clock. I think someone had been "playing...

Does anyone have an early revision CreatiVision they can photograph the PCB for me?

I'm trying to make sense of my PCB around the VDP clock generator area and I'm starting to think some components have been removed as there are traces that just go nowhere.
