I have an amiga 2000 with a 68030 gvp card, 8 mb of fast ram, ks 2.0, and a fat agnus... I'd like to use it as a demo machine, but most demos don't work. They either freeze or don't display properly on my ntsc tv. Is there any way I can make it more "demo friendly". Amiga monitors are pretty expensive, and so are scan doublers so I think I'm kinda stuck with the tv and a good ol a520 for now...:laugh1: Is there any way I can force the fat agnus to ntsc mode even when demos try to do pal? What about getting some slow ram?

If a demo expects PAL, it's got to be played in PAL. There's more to NTSC/PAL than just the video display. A lot of hardware-banging programs rely on the subtle timing differences between them, too. That could also explain the crashing. I think you need an Amiga monitor or a scandoubler.
Other things to consider, what era demos are you trying to run? If they're especially old, they might be getting confused by the 030 and Kickstart 2.

A2000 is not really the perfect demo machine. I faster processor i do not think is an issue but NTSC might. The AGA chipset is a bit different when it comes to NTSC/PAL and it's for sure a better demo machine.

You could try this if your TV can handle 50Hz mode.

@ Op
1. Most all north american tvs will NOT display PAL from your a520
2. The problem you are having with Demos is #1 they want PAL
3. Just get a 1084 monitor it shows NTSC and PAL and is the intended platform for properly viewing Scene Demos (RGB monitor)

The demos from Spaceballs work pretty well on a NTSC A2000 with 1 meg Chip RAM, 4 meg Fast RAM, 4 gig SCSI hard drive, OS 3.1, and no acceleration -- the machine we used at last weekend's Maker Faire. Many Maker Faire attendees couldn't believe that a 7.14 MHz Amiga could do all of those effects and music at really good speed.

This is exactly how I ended up spending loads on my an A4000. Watching demos on my A2000 was great until I started seeing the modern AGA stuff on the web. Once you catch that bug there's no stopping.
Worth it though :) (Jesus Christ Motocross anybody?)
