nd2003grad Posted October 30, 2016 Share Posted October 30, 2016 I recently installed the licensed 3.1 Kickstarter so I can use DF1 with Gotek (all of this and the machine are new--well, vintage new). I learned pretty quickly that I need a DF0 switcher--that's on the way. However, I'm curious about loading PAL/NTSC...am I correct in that you need a certain Agnus (I'm not sure on the number, but my other 500 has this and this one does not) to be able to select at the boot menu? I'm also not sure if Agnus is socketed--if so, maybe I should just swap the chips. My menu says "press a key to switch between NTSC and PAL," but nothing seems to happen. Once again this is on a FIVE HUNDRED! Thanks, guys. This is quite the journey, but it's already been quite rewarding. Quote Link to comment Share on other sites More sharing options...
oracle_jedi Posted October 30, 2016 Share Posted October 30, 2016 Correct. You need an 8372A or 8375 Fat Agnus chip which can switch between NTSC and PAL modes. Earlier 8370 chips could not do this. The chip should be socketed but be careful and ideally use a chip puller. I have used tiny screwdrivers to remove and reseat them in the past but PLCC chips are a little more delicate than DIP. 2 Quote Link to comment Share on other sites More sharing options...

I have used tiny screwdrivers to remove and reseat them in the past but PLCC chips are a little more delicate than DIP. Not to mention the sockets by now are brittle as hell. I have seen more than one 500 motherboard with a broken Agnus socket, obviously from trying to pry her out without using a puller. Quote Link to comment Share on other sites More sharing options...
Sinphaltimus Posted November 1, 2016 Share Posted November 1, 2016 No prying with proper puller, see my video comment here. https://www.facebook.com/SExmortus/posts/10206970892982775 1 Quote Link to comment Share on other sites More sharing options...

I'd been doing this for some time and your post helped me do this easily. THANKS! Now hopefully I didn't destroy the df0 selector that I broke a pin on and soldered back on (fingers crossed). 1 Quote Link to comment Share on other sites More sharing options...
Nebulon Posted November 10, 2016 Share Posted November 10, 2016 Once you have the new Agnus installed, there are a variety of utilities that will help you for switching modes, including Degrader. A couple of simple command-line utils are located here (NTSC and PAL): http://www.blitter.com/~nebulous/utilities.html 1 Quote Link to comment Share on other sites More sharing options...
nd2003grad Posted November 11, 2016 Author Share Posted November 11, 2016 Thank you!!!!! The entire project was a success--now have the df0 and the better Agnus, and have successfully booted from Gotek as df0 and switched between PAL and NTSC. Pretty good machine now! 4 Quote Link to comment Share on other sites More sharing options...
Nebulon Posted March 13, 2017 Share Posted March 13, 2017 Correct. You need an 8372A or 8375 Fat Agnus chip which can switch between NTSC and PAL modes. Earlier 8370 chips could not do this. The chip should be socketed but be careful and ideally use a chip puller. I have used tiny screwdrivers to remove and reseat them in the past but PLCC chips are a little more delicate than DIP. Just a minor detail. The 8375 is locked at NTSC and is not switchable. Quote Link to comment Share on other sites More sharing options...
