[The Poor Man's 1400XL Part 2]

I'm very curious as to why you chose the DIN7 and DIN13 connectors for this project? Why not a much more standard positive/ground power connector like the original, to fit a common 5v PSU, like from an old cell phone, or even keep the original and find a PSU that fits or splice in the plug from the original PSU? And why not just use a standard VGA connector for the VBXE output? It seem to me the ones you chose are out of the ordinary and far more complicated to make cables or find PSU's to fit. Is there some logic to your choices that I'm just not seeing?

Yeah, I never had a problem with my 1084S and my Atari's, of course I'm using NTSC machines or one NTSC with PAL Antic, but all work fine for chroma and luma. my 1084's sub-variant is 1084S-P

 

Are you aware that the 1200XL doesn;t have it's chroma attached? Without a video mod, you have to use composite for the chroma out. There's a simple mod for connecting the chroma line with the rest of the video-circuit as-is, if you don't want to do a full video upgrade like the Clearpic or SuperVideo upgrades. This is something I assumed you knew since you seem to be quite adept at upgrading, but I'm just making sure, especially now that I know it's a chroma problem and not luma. I'm guessing that hooking up to LCD is not through RCA chroma/luma inputs? If so, the LCD's are getting the composite signal for the chroma would be my guess...are you hooking up to the LCD's via composite or a S-video cable of some type (which might be using the composite for the chroma)?

I find the PAL screen (with my PAL ANTIC installed) far to squished looking, I have to adjust the vertical height so it's as tall as NTSC. Of course when I use games and demos that are overscanned PAL, I have to adjust the height again to see everything on screen!

Hello Flashjazzcat!

 

As you know from the main 8-bit forum, I'm repairing and upgrading a couple 1200's right now, so I've gotten excited about upgrades again since I have to take them apart for repairs anyway.

So, discussions with you have led me to your blog, just getting started here, but right off the bat I see something that piqued my curiosity. You say that you were having problems getting your 1084S to sync to the luma. I also use that same monitor, 1084S 50/60HZ (they all are aren't they), and I've never had any luma sync problems. (on a fully working 1200XL that is)

Can you explain further?
