eightbit Posted January 31, 2017 Share Posted January 31, 2017 I scored a really mint Amiga 500 and 1080 monitor (both boxed!) last week locally for $150. I have since added an HxC floppy emulator to it and carefully packaged away the original internal drive as I don't plan on using disks....just images to play games. It is not yellowed at all and looks like it have never really been used. It is using Kickstart v1.2 which is cool as it is just like my first A500 It is a unit with a 8370 Agnus (NTSC hardcoded) with no PAL abilities unfortunately. After much reading, it appears I can swap the 8370 NTSC agnus with a PAL 8371 agnus, so I found and ordered one for the amazing low price of $4 I have been reading online in some forums that while some people recommend changing the oscillator to a PAL version, others say it will not matter much as it is still within video tolerances. I have a good PLCC extractor so I guess it won't hurt to just try it. Has anyone here tried popping a PAL 8371 into a REV 5 board with an 8370 NTSC before? Just curious as to your results. Essentially I am fine with completely turning into a PAL machine if this works as I expect it to. Quote Link to comment Share on other sites More sharing options...
eightbit Posted January 31, 2017 Author Share Posted January 31, 2017 I think this explains pretty well what an NTSC oscillator using a PAL Agnus and vice versa will do: http://www.amibay.com/showthread.php?75138-NTSC-vs-PAL&p=717159&viewfull=1#post717159 It won't be "true" PAL, but it will be PAL for most intents and purposes Quote Link to comment Share on other sites More sharing options...
rootboy Posted February 3, 2017 Share Posted February 3, 2017 After reading the Amibay post, I'd say just swap out the Agnus and go for it. BTW, nice score on the A500 and monitor! 1 Quote Link to comment Share on other sites More sharing options...
Zippy Zapp Posted February 19, 2017 Share Posted February 19, 2017 Can you swap out the Agnus for an 8372A? I think, IIRC, it will work. The 8372A supports both PAL and NTSC... Quote Link to comment Share on other sites More sharing options...

That is a good question. I am not sure if it will work with this revision but I have to research that. Thanks! Quote Link to comment Share on other sites More sharing options...
+remowilliams Posted February 22, 2017 Share Posted February 22, 2017 That is a good question. I am not sure if it will work with this revision but I have to research that. Thanks! Since you have an ACA500plus, what you want is an 8372a Fat Agnus... Quote Link to comment Share on other sites More sharing options...
eightbit Posted February 22, 2017 Author Share Posted February 22, 2017 I have since replaced the board with a Rev 8A A500+ recapped motherboard so this is no longer an issue The ACA500+ works fine with the new board as it has a newer agnus.

Nebulon Posted March 13, 2017 Share Posted March 13, 2017 That is a good question. I am not sure if it will work with this revision but I have to research that. Thanks! I've done this on a number of Rev. 6 boards and it worked fine. <-- for anyone out there curious to try it. Both the 8371 and 8372A worked great.
