Boards ordered. Now to sort through components... :D

2 boards also ordered for a friend intrested in building them. He helped me with the first boards and will now have his own to build as well...

OK, I have stripped a few ST boards now so have the Atari chips and connectors. I have also ordered components from Mouser AU and other places so should have all BOM components in hand.

Boards are in the post on their way to AU so have to wait now...

I am avidly watching the builds under way at the moment for the fixes that will need to be done.

5 boards have arrived safely in AU. Many thanks to @exxos. 2 are mine, the other 3 are being passed onto a couple members of our local Atari group. We are all excited to be involved in this project. :D

U2 (SN74LVC1G11DBVR) IC in place. Managed to lose one on the floor and it is so small I could not find it!

I think that is all SMD components now on both my boards including resistors and capacitors. Unless I have missed some?

Is there a short on the bottom left pins of U2 ?
