16MHZ OPTIONAL FIX

Got the wire a little too hot here and melted back the insulation further than I'd like, but nothing risky is nearby, so it'll do.

(Yes, I did just cut that resistor off at the board instead of desolder it.)

Quick question about the GLUE DATALINE FIX...

In step 1, it says, "Cut D0 & D1 tracks on the bottom of the PCB" and the red indicator covers two tracks in the picture:

Is it correct to cut both tracks covered by the red line, not just the yellow track? Since the instructions say to cut D0 and D1, and the non-yellow track goes to D0, I think I know the answer, but I want to double check with you guys before I cut. :?

Yes, cut both tracks :)

If you zoom the image, you can see D0 & D1 on the IC holes.

Yep, I did see the labels. Just wanted to be ultra-sure before cutting. Thanks! :)

So, life got in the way and kept me away from this project for a long time. I've finally picked it up again and made some progress, although I'm not getting video (more on this later).

For now, various pullups and the GLUE dataline patch (don't ask about the bits in the corner):
