Is there a jumper on the Amiga 2000 like on the A4000 that allows you to "lock" the computer into either NTSC or PAL?
So putting a toggle sw on these two contacts will keep in in PAL or NTSC depending on where you have the switch set? Now that I have changed the startup and have the reboot line in there to accommodate the new libs PAL wont stick in the early startup menu if booting into workbench so this would be a good workaround.
