I had forgotten about Midi-Maze, way ahead of its time!

Thanks, I actually figured it would be sync and happy to report I have successfully got beautiful RGB out from my XL very pleased, thanks Simius! Behold my Gyrus running at SCART to 1080p HDMI...

Hi Simius, my Sofia is installed and up and running. I have mounted the DB9 successfully in the bottom case, I do have a couple of questions: 1. I'm starting the SCART cable tonight, in your wiring diagram it shows you are also passing through Composite Video. Is this required as well as the RGB? I'm concerned my HDMI converter will pick up the Composite video instead. 2. When installing the Sofia it sits high with the GTIA piggy backed on it and couldn't re-fit the top shield to the XL, is this safe and expected?

Thanks! Your awesome.

I had tried re-seating it first, but no go, the donor XL was in poorer shape than I was led to believe, missing its Sally and Pokey chips, and internal shield, did not want to risk my good components in it to test, so not operational. I was lucky that the GTIA and ANTIC were still there. I fitted the faulty GTIA in the donor for now.

Hi, which pin does Sofia RGB use for Audio? I assume its pint 1 looking at the plug, Do all Revs of the board use the above pin outs? I'm trying to figure out how to wire up a SCART cable for it as my board did not arrive with the cable or any docs...

Thankyou! You were spot on. Replacing the GTIA fixed it. Very happy.

This is the coolest thing I have ever seen

H Hi , is this still around, where can I purchase one?

Thanks I have a second 800XL for parts coming, hopefully this is a socketed GTIA too, or if its working might just swap out the entire motherboard.

Heres a clearer photo of the issue, the issue starts after a number of sprites appear.

Thanks, I am beginning to think the GTIA is the issue.

Joust fails immediately with one following the main player, it was one of the first I tried. This also appears straight away with Zaxxon, Gyrus, Attack of the Mutant Camels, Poll Position . However Loadrunner, Hero, Defender, Gallaxian, Starquake, Rampage, ChopperLifter, Dandy all run fine.

Hi, I have recent purchased a 800XL (PAL) and paired it with a SIO2SD external drive, all appears to work fine, expect on a lot of games I'm getting a corrupted sprite, and I'm not sure why, would anyone be able to shed light on what may be causing this? Configuration, software, PAL/NTSC issue, RAM or Antic failure? Note that some games appear to run perfectly. Also passes memory tests fine. I apologize for the poor photos, but you can see the corrupted missile or sprite running vertically down the display, these will follow the player or enemies. Any help would be appreciated.
