Looking good!

Reminds me, 3M have discontinued their THT sockets. Time to buy a bunch, before they disappear.

And, then, by extension, this!

Pico based ISA video card!
The last update emulates a Cirrus Logic CL-GD5429

That is so cool! Be good if it had VGA output too.

@agranlund

Could you kindly add a changelog for A2 to the Raven's github README or docs dir please? I found a (partial) changelog on p155 of this topic, for anyone else wondering whats new since A1.

Amazing work, congrats on the new board.

Thanks

Excited to hear more about the A2 bringup, hope everything works as expected!

Thanks! Obviously I missed that.

I want to build one of these but not until Anders has verified it.

Me too! With some luck I hope it'll show signs of life this weekend.
It's starting to resemble a computer now, or a murder scene with all that sticky flux all over the place :)

Only a few connectors left, a pass in the cleaner, then soldering the few remaining parts that i dont want exposed to the ultrasonic cleaner.

Wow, great progress! You are quick. And I know what you mean with the sticky flux, almost impossible to get rid of just scrubbing with IPA. Haven't bought an ultrasonic cleaner yet but maybe I should :D

Very likely my technique isn't all that good but I really have a difficult time getting large boards clean with manual scrubbing and IPA.
This will be the first time trying the ultrasonic on a board this size so I'm quite excited to see what the result of that is.

I used some no-brand sockets in my Rev.A1 build, and now the 3M ones for Rev.A2.
Was surprised how much force is required to seat chips in the 3M version - I take that as a good sign and may also pick up a few more before they disappear :)

It lives! :)
Incredibly satisfying, after hand soldering all these individual components.

Fingers crossed all the old and new features are working as they should.
Especially excited about verifying DSP and related stuff.

:cheer: :cheer: :cheer:

That's great news. I'm slowly putting together a lot of parts for when I build another Raven
