Amiga 2000 rev. 4 - any use upgrading it?

I'm guessing it's the German 4.0 or "A" revision that the guys above have mentioned. This was my first Amiga I got and I had endless problems with it. As Ral-Clan has mentioned, it uses the A1000 chipset with the "Thin" Agnus that can't address more than 512K chipmem. A lot of WHDLoad games (probably most) require at least 1Meg chipmem.

It doesn't have a Buster chip, so the signals on the expansion slots are very noisy and gives a lot of problems with various expansion boards. When I had my GVP A2000 HC+8 card in it, it would randomly freeze up when playing games or loading games off the HDD. I swapped out the MOBO for a Rev 6.2 board and haven't looked back, my A2000 is now 100% stable.

If you're able to get one cheaply, go for a Rev 4.3 or 6.2 motherboard. They're fairly common and will make your A2000 far more usable.

If I upgrade the board to - let's say 4.3, then it won't fit in my case since the 4.0 board only have the 2x sound outputs and all the others have 2x sound and 1x mono composite.

Ah, yes, I did forget about that! I upgraded the mobo a long time ago. I didn't really want to do it, but I modified my case to allow all 3 phono plugs out. I was in the same situation as you then, very few A2000's available in South Africa and wasn't prepared to pay the shipping costs for such a heavy beast, so I just modified my case.
