Last two Phoenix Shifter V2 prototype components assembled this morning. A few solder bridges to sort out and final assembly to complete this weekend. These will be the last ones of this version as we have the V3 PCBs and components on order.

@Icky i know a man who has some good tips for removing those solder bridges.

I need go try mine again with a TF536 and see if it works. Would make the ultimate H4 with this added as well.
If it ain't broke, test it to Destruction.

@PhilC, funny I was just thinking of doing a video of removing the bridges with the method I have found. It’s so easy. I never got on with braid and other methods.

@Icky you should, its a top tip. The only time I now use braid is when I'm too lazy to start up the desoldering gun.

@Icky I would also be very interested in the desoldering method you use!

Will this wonderful device work with Freesync/G-sync monitors to display 50Hz? Since almost all of the regular modern monitors will do 60Hz only. I wonder if it will be that simple...
I'd definitely buy a dedicated monitor if this will work since they're not expensive anymore these days.

Thanks @exxos for sending over the boards from the manufacturer. Comparing to the older board size its a lot slimmed down and we have managed to pack in the audio codec / mixer chip as well. In addition the Micro-JTAG boards viewtopic.php?f=18&t=1718&start=10#p44580 were also in the the batch.

Now I just need to find some Atari time which has become very scarce over the last month or so to build these :(

Am not looking forward to having a go at the MBGA chip but its going to be an adventure no doubt.

Well thats the easy side SMT components soldered using the higher temp solder paste. Just a little clean up needed as I have spotted a couple of solder bridges.

Well that wasn't fun and must be the smallest, most dense work (MBGA) I have done so far. Just need to give it a clean and then see if it works or ends up in :fire:
