I have a "European version" of the Amiga 2000 and a 1084S monitor. I'm trying to run a Video Toaster on this system but it doesn't work. I think the problem is that the toaster can't sync itself because the European version is based on PAL rather than NTSC (I do know that the Amiga wants NTSC and will be using NTSC video sources). Has anyone in Europe got a toaster working? What changes to I need to make to the Amiga?

Here's how to convert your PAL Amiga 2000 into an NTSC Amiga for use with the toaster: This procedure voids you warranty so you probably want your dealer or service center to do the modifications. Although I did this with my A2000, I cannot guarantee that this will work with your model/motherboard etc. In no way will I be liable for any damage to your equipment... 1) If your A2000 only has TWO cinch connectors on the back (i.e. no Mono Video connector), you have an A2000A - this model cannot be upgraded. Sell it as fast as possible... 2) Type "avail" in a shell. The output of the first two lines should look like that: Type Available In-Use Maximum Largest chip 807472 232680 1040152 806568 ^^^^^^^ This number tells you, how much CHIP memory your A2000 has. If "avail" reports another number (about half as much) for maximum chip memory, you have an older A2000. If 'Maximum' shows '1040152' skip to point 4). 3) It is possible to upgrade such an older A2000 with a new Agnus chip. The new chip that handles both PAL and NTSC is called 8372A. (Your C= dealer should be able to get this new 'Super Fat Agnus' for you. Hovewer, you'll need a chip puller tool to swap the chips. To use 1 meg of chip memory, you'll have to change jumper J101 so that pins 2 and 3 are connected. 4) For NTSC, Jumper J102 (on the left side of the big square Agnus chip) has to be in a closed (i.e. connected) position, for PAL it has to be in an open position. Some Amigas don't have real jumpers but the trace is marked with a rectangle and "J102". You might want to install a switch to change between PAL and NTSC on the fly. Quartz (28.37516 MHz) ---- ----------- | | | | | | | 8372A | | | | | ---- | Fat | | Agnus | O-O | | J102 ----------- There's no need for swapping the Quartz although NTSC machines have a slightly higher clock rate. The toaster does not rely on this clock cycle. >Internet: simon@cui.unige.CH --Martin -- Martin A. Blatter blatter@ifi.unizh.ch

I wouldn't suggest switching the switch with the power on however. <grin> > -- > Martin A.
