Is it possible to change a NTSC-amiga (american version) into PAL? And what about the power supply? Can it be changed? (From 60 to 50 Hz) -Frank Tore Johansen -- (Argh, /dev/null ate my signature :-)

Which monitor do you own? The C= 1081 will aotomatically adjust itself to the PAL or NTSC standard. You can also manually change the vertical size of the C= 1080 by an internal control. You also have to change two things on your 2000 motherboard. The Agnus (8361) chip (I don't know about the fat agnus), and the system clock. NTSC' clock run at 28,63636 MHz and the PAL' clock run at 28,37516. You should contack your C= service center for doing the chip swap. They will inform you about the part numbers of the cristal and the Agnus(FatAgnus) chips. Good luck, Edouard Boily Dept. de Physique Universite Laval Quebec, CANADA

Well it isn't just on the 2000. Any Amiga (500's are being shipped w/ the 1 meg Agnus chip) with the 1 meg Agnus chip can switch into PAL mode. Using the program called PALBooter, you can boot as if you were in PAL mode. There is a slight flicker (freq change?), but that is all. > You also have to change two things on your 2000 >motherboard.

You do have to change to make sure you have the 1 meg Agnus chip. How do you tell, you ask? Well you should have 1meg of chip ram if you have the fatter Agnus (but not necessarily. I have the chip but 512k chip & 512k fast ram). If you still don't know just try booting PALBooter. You will be able to tell if it works. > You should contack your C= service center for doing the >chip swap.
