Pal Agnus in NTSC A2000?

[Iggy]

Can I use an 8372A Pal Agnus in my US Amiga 2000?
If so, is there a simple way to switch between Pal and NSTC modes?

8372A are all dual PAL/NTSC, the default mode is set by a trace on the motherboard & can be changed at run time.
 
I'm assuming you already have an NTSC 8370, in which case yes.

J102 on the motherboard is used to switch between PAL and NTSC.

Great! I bought one and wasn't 100% sure.
Yep, swapping out a 8370 for the 8372A.
I wanted to upgrade to an Indivision ECS, and this component was necessary.

IMHO try to score yourself a MegaChip of some sort (8375 on an adapter board with extra memory chip, gives you up to 2MB chip ram).  Once you get your Indivision you're going to want to make use of the higher screenmodes it supports, and the extra chip memory is very useful for that.

How many colors can you use with an ECS machine and Indivision ECS?  ie how many colors on WB?

Indivision ECS supports 800x600x16 color Workbench under ECS.  Best with an accelerator and some extra memory, obviously.

I've considered that, but MegaChip boards are hard to come by and when they do sell its usually for a high price.

Go chuck a dollar coin across the river on July 4th and see if GW's Karma let's you surprise the British with a favored sale on Amibay.

MorphOS isn't Amiga, its MacOS done up with more LSD and THC.

i think I'll just stick with the 1 meg upgrade.
I've also ordered an 8373 Super Denise, so I'll have most of that ECS goodness.

If you are going to use an  Indivision ECS, you don't need one.

I know, but funds are tight right now, so the Indivision ECS will probably have to wait.

@Iggy,

I took the jumper off my amiga's ntsc/pal jumpers and hardwired in a switch which now allows me to power up in either mode for different programs, just make sure the unit is off when you flip the switch.

What happens if you don't?

It's perfectly safe to throw the switch while powered up. I've done so hundreds of times (A500 and A3000) and after all, it just toggles a bit flag.
However, it won't have any effect until the next reboot.

Contrary to common belief, it's also quite 'safe' to switch Kickstart ROMs, the A19, or the _EXRAM option while powered up. 'Safe' in the sense that it won't cause any permanent damage but only crash the system violently.
