The replacement regulators work well and solve the power off problem. I've been testing the luma trap response with burst test patterns generated in the FPGA. The hardware is working well, but I am starting to think the trap may not be worth it for retro-computing. It softens the edges of the characters a little, but does reduce the colour...

A quick update, I apologize for the delay. I've been really busy testing the boards.
No real problems as yet. I'm waiting for a different LDO as the one I am using does not shut down when the input power is turned off, and the resulting reverse leakage keeps the board partially powered. I have modified one board with a different...
A few more pictures now I've assembled the through hole components.
You can see one board does not have the components on the backside, this is the version without the composite/SVHS output. The board you can see from the top has the codec and the extra output connector. Note, I've stuck four rubber feet on the bottom over the mounting holes...
The first 10 prototype boards came back today. I will post some more pictures after final assembly tomorrow...
Good news, the missing connector which was on 3 month lead time has finally arrived! The components are packed and shipped off to the production people for the prototype assembly. The paste mask needed for assembly has also arrived, so we are good to go.
Hopefully I will have the first few boards to test late next week.
I was on a...
I'll just sneak in a little update while it is still August :)
Well, late July didn't happen never mind early July. All of Sweden seems to shut down during the summer, and getting a production slot has proved difficult. However, we are going ahead now. If the missing connector arrives this week we could have boards next week, but more...
No news at the moment, I am still waiting for an assembly slot. It looks like I'll get the boards back early July.
I'll be out of contact for a few days, I'm off to Glastonbury music festival :)...
Well, I made it back from China with the boards and a lot of the parts.
Now I'm going through the pricing and starting to kit for assembly.... New connectors seem to fit ok :)...
