Chip ram

[Retrofan]

Hi:
Just a newbie question:
Why it's impossible or so difficult to increase the chip ram in an A1200?

It is imposible due to hardware limitations to increase chip ram. The only things you can do are:
1. Use some program/patch/hack to reduce your chipmem usage.
2. Get an RTG gfx card for your system and forget about chipmem alltogether.

If you mean free up Chip RAM, having loads of fast RAM and being scrupulous about what apps you use and how you use them will leave you with hopefully lots.

If you mean actually increase the amount of physical memory, forget it.  You can't.  The AGA (and ECS) chipsets max out at 2mb, period.

Implementations have been worked out in WinUAE to allow more; IIRC the MiniMig AGA allows more chip RAM, too.

But on an actual 1200, you're stuck there.  It's a physical hardware limitation.

And the gfx card always has to be through a Zorro connection? Can't it be made internally for a desktop Amiga?

Yes,

There was/is the Bvision which works exclusively with the Blizzard PPC acclerator, but while it my physically fit in the desktop case, most people still towered it to fix cooling issues.

Thanks. I've read about them, but I wanted to know this details.
Everytime I look for more I always find the frontier of the PPC... and 500-600€ are quite too much...
