In your case, it's a direct replacement. We deliver ACE2b with both types of Agnus (Vbb and non-Vbb). You're in the lucky positino to have a PAL-non-Vbb Agnus and a non-Vbb Agnus on ACE2b. It'll work, but you'll void your warranty, so you should at least test the unit and wait with your mod until the revocation period is over.

Thanks for the prompt reply.
In that case is there a mod I can make to the CDTV motherboard to force it into PAL on boot, instead of entering the ESS.
-
You'd have to patch Kickstart to do the write to the register(s).
-
Interesting!
Could you point us in the right direction of how this could be done?
-
Sorry, but that's beyond the scope of normal product support. The solution for this customer is obvious: Just replace the Agnus chip with what you have. Why leave the effortless route?

No pin isolation required - it will always start in NTSC mode. If it were that simple, I would have added a jumper to the design
-
Thanks Jens, so to be clear, there's no way to force it to startup as PAL, you can only do the switch via the Kickstart boot options or via an ACA500 add-on ? The idea for the pin 41 method I was thinking might work is highlighted by GadgetUK here, https://youtu.be/mKQw5z3vUNA?t=149
The reason I want to be clear is that I'd like to keep my A500 rev5 PAL with a KS1.3 setup with newer kickstarts being an optional feature rather than required. And my desk setup doesn't have room for a side-expansion like the ACA500.
I just want to be clear on what to expect before I make the jump, Thanks Jens

Pin#41 only applies to the ECS 1MB Agnus model, not the 2MB model. The only way to switch to a different mode is to write to the Agnus register that tells it to switch to PAL, yes.

Hi!
Hijacking this thread a bit. Today I received an ACE2b from a Swedish reseller. Sadly I didnt read up on the product before ordering and just after receiving the product I noticed a label saying NTSC on the box. I called the dealer and he informed me that all ACE2b's are NTSC as default even the ones sold in Europe.
Since I dont want that my question is - Can I swap the US-version Agnus (NTSC and VVB) for an European one that I have (PAL non-VBB, 390544-01)? Is the removal of component C9 the only modification I need to do to the ACE2b?
Thanks,
Bjorn

Yes and yes.
Please understand that the product warranty will be void, so please be extra-careful when removing the NTSC Agnus to not damage the socket. Also, I recommend to take a few pictures to have a record of which way round the chip was inserted.
-
OK, thanks for the reply Jens!
I will of course use the correct tool for removal and also test the product before. I understand that the warranty is no longer valid.
