You can connect up a switch between the leads of jumper J500 and switch between NTSC and PAL video. Of course you must power down your machine before you do any switching. This works just fine on my A2000. -- Bob _________________________ Pro-Graphics 201/469-0049 __________________________ UUCP: crash!pro-graphics!bobl | ProLine: bobl@pro-graphics InterNet: crash!bobl@pro-graphics.cts.com | CServe: 70347,2344 ARPA/DDN: crash!pro-graphics!bobl@nosc.mil | AppleLink: Graphics3D ___________ ____________ Raven Enterprises - 25 Raven Ave. Piscataway, NJ 08854

Cut jumper pad J102 or make pin 41 (TEST) of the Agnus a no-connect to get a pal machine. You must have the 1Meg-Agnus to do this. -ken. -- -------------------------------------------------------------- Ken Farinsky -- CATS Commodore Business Machines PHONE 215-431-9421 UUCP ...{uunet,rutgers}!cbmvax!ken --------------------------------------------------------------

You must have the 1Meg-Agnus to do this. Sorry about that mis-information, it IS jumper J102 that you should connect the switch to and NOT J500. I was using my feeble memory to remember the jumper I had connected up. > -------------------------------------------------------------- > Ken Farinsky -- CATS Commodore Business Machines > PHONE 215-431-9421 UUCP ...{uunet,rutgers}!cbmvax!ken > -------------------------------------------------------------- -- Bob _________________________ Pro-Graphics 201/469-0049 __________________________ UUCP: crash!pro-graphics!bobl | ProLine: bobl@pro-graphics InterNet: crash!bobl@pro-graphics.cts.com | CServe: 70347,2344 ARPA/DDN: crash!pro-graphics!bobl@nosc.mil | AppleLink: Graphics3D ___________ ____________ Raven Enterprises - 25 Raven Ave. Piscataway, NJ 08854
