Don't worry, you might be able to fix it if you got a soldering iron. Try checking the continuity of that trace first.

@Eivind, would you consider adding the changes for the wavetable? In ITX case things are much easier. We just need the DC2DC to provide the +/-12v and a jumper to switch between 3v3 and 5v Midi-in.

Sweet. Got it working! Thank you Eivind First I tried with removing R30 and R29 and things worked. But then I put the resistors back and added two NPN-Res (Q2 and R28, R29 from TL2 BOM) inverters back to back and things now work for both the Pi and DB50XR. Conclusion, DB50XR requires the -/+12 ( …

I got the +-12v working, but still no sound. Anyone got some experience with DB50XG and what is takes? Should I buffer up the midi signal from 3v3 to 5 ("TTL")? I doubt that makes any difference, however I need seeing other people put an optocoupler like 6N137 on that line. Any suggestions?

@Eivind, I am trying to get the Yamaha Wavetable to work on the TL2 Wavetable adaptor and I need to have the +-12v for it. Any chance you can share the board with me so I can make those changes

Sooo amazing guys. Can I get a copy to test it on my hack (passing auto via HDMI?) Also, can we have all these (or some of them at least) BIOS menus on the TL2 please? I love the TL2

Surprisingly, my cheap HP monitor (M22F) works so well with it but my ROG does not even recognize it.

And I got the SM-750 with HDMI output to work. Yay! Now I want to inject the audio over the HDMI cable as well. Not sure if that is analog and digital. If digital, I need to figure out to do the conversion first. Cool that you got it working! I'm curious about resolutions and refresh rates though - …

I'm currently trying to get S/PDIF output working on the ITX-Llama, it's not that straight forward. I'm getting invaluable help from 640K!enough though, when we get it working I'll see if it's possible on the TinyLlama as well.

[/quote] Are you talking about the TinyLlama or the ITX-Llama now? (This is the thread for the latter). I wouldn't think there'd be much use for the ethernet/slip firmware on the ITX-Llama given that it already has a built-in real ethernet port...? [/quote] My bad, I did not notice that the is …

So, I kept digging and I found that I can feed the S/PDIF to the SiI9022A on the Graphic card which is an HDMI transmitter. Then I looked into the CS4237B and noticed that it can provide the S/PDIF output. So, I did some soldering, but not results yet. I used /XOS1 and no luck. (still digging). I do …

As always, amazing. Here is what I got: https://www.icop.com.tw/product/VEX2-6454 Some more comments/suggestions There is an amazing package of DOS games called REMOVED .

The new board and case looks great! Its the complete package now. Looking forward trying both out. I tried out a bunch of different PCI graphics cards for fun. A few worked OK and some had the exact same freezing issue with 640x480 and above resolution in games like quake and duke3d that I saw on …

Eivind, I got my hands on a Vortex86EX2 and it took similar to the Vortex86EX but with the additional core that uses the dual port RAM. I do not see anything significant in it in compare to its predecessor. Is that the reason why you mentioned that you do not thing about it as an upgrade?

@ExplodingLemur: I just have to use a stronger USB-C adapter. Nothing really much. Again, just with a bad USB-C you will not get anything or a messed up image. This is the one I used: https://www.ebay.com/itm/295434434943 . In case you want to have fun with crimping, I added a picture of the wires …

I have been thinking about a hardware based virtual CD that does the job of SHSUCDX. Would you guys think that would be a useful thing for the Tiny Llama project?

sneak peek If anyone wants to use the Waveshare 1.51" Transparent OLED, you need some hardware modifications since the board comes with SPI mode enabled and you need I2C. Here is the list: Move the two zero-ohm resistors to the I2C setting. Connect DC and CS to GND Connect RST to VCC Remove the two …
