adam242 Posted September 9, 2012 Share Posted September 9, 2012 I've been wanting to do the PAL upgrade on one of my machines for some time now... Dying to play Marbled, among others, on real hardware. The Nir Dary upgrade consists of replacing the ANTIC and OS chips - since my 1200XL already has the Atarimax Warp+ 32-in-one OS mod, can I simply swap my ANTIC chip out for a PAL version and switch in one of the PAL OSes from my Atarimax menu? Seems like a no-brainer to me, but maybe I'm missing something. Quote Link to comment Share on other sites More sharing options...
mimo Posted September 9, 2012 Share Posted September 9, 2012 Just stick the pal antic in the socket. You don't need to select pal OS . However, you will need a monitor that can handle the pal signal Quote Link to comment Share on other sites More sharing options...

MEtalGuy66 Posted September 9, 2012 Share Posted September 9, 2012 (edited) yep.. you might have to slightly adjust the vhold, but other than that, it's fine.. It doesnt have to handle the actual PAL chroma signal.. Your machine still has an NTSC GTIA.. It just needs to be able to handle the additional scan lines Which works just fine with a 1702..

adam242 Posted September 16, 2012 Author Share Posted September 16, 2012 Thanks for the info, guys... I've bought my chip from Best and it does indeed work without swapping OS and syncs fine with my monitor. However, some games run noticeably slower (Yoomp! is particularly objectionable) now. Is there a (relatively easy) fix for this? I've searched the forums for posts related to ANTIC swaps, but I can't find an answer. The topic of timing issues is barely mentioned... am I just hyper picky? Ideally, I'd like to have both chips in my machine and be able to switch between them. I know this has been brought up before, but again, no definitive answer. Quote Link to comment Share on other sites More sharing options...
Gunstar Posted September 16, 2012 Share Posted September 16, 2012 Yeah, you will have to get used to some games running slower with the PAL Antic, this is the downside of PAL; while it may provide higher-res but some games run slower. This is the reality of PAL with a 50hz refresh instead of 60hz. You will get used to it though, it's just a bit shocking at first. There is no easy fix, you can only replace the NTSC Antic to run NTSC compatible games. On the other hand, games designed for PAL are running at their designed speed, and actually speed up if they can run on a stock NTSC machine. The Pal Antic runs PAL software at the correct speed, and NTSC software a bit slower. Quote Link to comment Share on other sites More sharing options...
mimo Posted September 16, 2012 Share Posted September 16, 2012 Swap to an NTSC antic Yes pal is 17% slower, and really noticeable in some games such as pacman, At least you can play dropzone properly now, and watch some great demos Maybe get another machine so you can have one of each?

adam242 Posted September 16, 2012 Author Share Posted September 16, 2012 You're both right... I can learn to live with it. I can run Marbled without an emulator, and Dropzone is actually playable now! It's not like I have a shortage of other machines to use in stock NTSC form. I think I'll keep the tricked out 1200xl as my PAL machine, and when my Incognito board comes for my 800, I'll have a kick-ass NTSC box.

sargie Posted September 16, 2012 Share Posted September 16, 2012 Sounds interesting to me too. Couple of Q's. 1. I have a 1200 with the multiple OS upgrade. Is the Antic socketed on a 1200 or do I have to de-solder? 2. Where do I get a PAL antic? Thanks! Sarge Quote Link to comment Share on other sites More sharing options...
MEtalGuy66 Posted September 16, 2012 Share Posted September 16, 2012 (edited) 1. Yes the 1200 should be fully socketed. 2. You have to order it from the Polish Atari Legion. (Hence the term, PAL).. They developed their own special ANTIC chip to allow ataris to work with televisions and displays in Europe..

mimo Posted September 16, 2012 Share Posted September 16, 2012 1.Parts Accumulation List 2. Try Best Electronics http://www.best-electronics-ca.com/custom-i.htm CO14887 (PAL ANTIC) $10.00 Quote Link to comment Share on other sites More sharing options...
