Re: Lead-free soldering

I still use classic 60/40. Over here in Australia the more we can do to damage the environment, the more we like it!

Take that, groundwater table!

Re: Project: HDMI/DVI out for STFM

I've seen the same effect on pretty much every pirated game, and as far as I know it works fine on HDMI. Spectrum 512 also uses the background colour to show bars, but it's a semi-static effect. I only use HDMI so I have no easy way to compare the two setups.

For the screen border afaik always palette entry 0 is used, so you'll see whatever color is programmed into that entry.
Yeah, I think you're right. I have no theory to explain that behaviour.

Re: Project: HDMI/DVI out for STFM

I don't have a "default" palette in the FPGA shifter. Maybe there's a default palette in the real shifter, and you're seeing those colours. It's something I can add.

Re: Project: HDMI/DVI out for STFM

That's interesting. I'd like to know more about this. I take it this is a program that works with or from a diagnostic cartridge?

Re: Project: HDMI/DVI out for STFM

It has been a while since I posted here. Not much to update the world on, but: There are now four prototypes in four countries I'm pretty sure I've fixed the 1 pixel misalignment of the screen in fullscreen 640x400 mode (needs to be confirmed for all wake-up states) I've sent Troed a replacement boa...

Re: 1040 STF showing occasional rogue pixels

- Given the fact that the corruption is only visible in the part of the screen that doesn't get redrawn every frame and that the pixels don't change location, I think the RAM isn't faulty, it must be the transport to it that has a problem. The shifter simply displays what's in RAM and does so consi...

Re: Project: HDMI/DVI out for STFM

Congratulations Troed on finding this valuable bit of evidence, it seems like we are narrowing down the problem quite a bit today! I assume the FPGA-Shifter is already able to output the contents of the palette registers Yep, it's working fine here. I discussed this stuff a bit with Troed earlier in...

Re: Project: HDMI/DVI out for STFM

Is it possible that the difference is that when running with the FPGA connected, there was no plug in the video out socket, while when you were running an original shifter you always had one plugged in Hmm, that doesn't make enough sense. I should have thought about it for longer. The plug only gro...

Re: Project: HDMI/DVI out for STFM

Wow. It absolutely is. Connected up an HxC slim to my beautiful internal floppy header in the 520ST and booted ... Closure. No resets at all. So previously I had looked at /MONOMON with my LA to see if it triggered - since one of the few ways an ST resets cleanly is when TOS detects a mono monitor ...
