pjbramley Posted August 1, 2014 Share Posted August 1, 2014 Was considering purchasing a 1200xl to add to my collection, but know a pal version was not produced. Is there a way to view a 1200xl in Australia? Would it work through the monitor port or is there some easy to install hardware upgrade available?

flashjazzcat Posted August 1, 2014 Share Posted August 1, 2014 Begin with one of these, if you're capable of some light soldering (the main crystal on the motherboard needs replacing, and possibly one jumper): http://www.bitsofthepast.com/?product=gtia-pal-adapter-8001200xl-2 Replace GTIA and Antic with their PAL counterparts and you're done. The video quality can be further improved, but that's another story (search "Clearpic 1200XL"). 1 Quote Link to comment Share on other sites More sharing options...
Mathy Posted August 2, 2014 Share Posted August 2, 2014 Hello guys IIRC you also have to convert your 1200XL to "one ROM". The 1200XL seems to have a two ROM OS, which doesn't understand that it should talk PAL instead of NTSC. (OK, please somebody explain how this works, as I'm only repeating what somebody else said (and I didn't quite understand)). Sincerely Mathy Quote Link to comment Share on other sites More sharing options...
Rybags Posted August 3, 2014 Share Posted August 3, 2014 Main issues with a dedicated OS ROM or one that thinks it's on the other system (e.g. swapped Antic but not GTIA) are key repeat rate to slow if swapped NTSC to PAL, and Pokey counter values for cassette reading will be wrong (supposedly though, this isn't a big problem since there is some speed leeway allowed by Pokey serial input) Changing NTSC to PAL means the key repeat becomes annoyingly slow but at least XL/later OS has the RAM based speed variables so it can be changed by program or the user.

pjbramley Posted August 12, 2014 Author Share Posted August 12, 2014 Are monitors designated as being Pal or NTSC or are they universal? Quote Link to comment Share on other sites More sharing options...
mattlacey Posted August 13, 2014 Share Posted August 13, 2014 Don't know if it helps or not but I've got an NTSC 800XL running fine on my Australian Samsung Series 5! Quote Link to comment Share on other sites More sharing options...
