The reason I asked about the memory is because I have a simlar setup to you and I'm also new to the scene like yourself
Let's talk about the A604 first of all. With just the A604 in place with the ECS in place I have 1,440,070 or there about meaning that I have 2Meg of chip mem. The other mem is showing 0 After messing with the setting in WinUAE I think this is correct. (anybody else please feel free to correct me otherwise) As for the chip missing so is mine however if you look on the two different pictures you have the other chip is missing in the upper left and is in place in the other picture.
As for the delock. I found that when plugging it into the A600 I was able to put it into two different position into the motherboard. Apparently this is common. As for my own configuration I'm getting a lot of 1111 Error which from all accounts seems to be a hardware issue. Anyway I hope this helps somewhat.
Cool to hear that more people have found new interest for the Amiga (and OCS/ECS)

~1,400-1,500 chipmem sounds about right when running WB. The other mem is fastmem (and slowmem?) so no increase there until you get some fastmem expansion (like with the ACA620 accelerator). Yeah, the "missing" RTC chip wasn't that missing afterall

.
I found this in the ACA620 thread: (

Here is a curious side effect. My A604+Indivision ECS would not work before on this mobo (although they worked fine on a 1.5 mobo). The extra chip mem was not recognized. Since I installed the ACA620, the expansion and the scandoubler work just fine. Now this is mind boggling. I have no clue why.
Hope this will be true for me too as I have an ACA620 on its way. Sounds a bit unstable though. What then when the ACA620 is disabled. Hm.
You mean multiple IDE connectors? I only have one, the same one I use for the HDD. I used that one out while testing the CF, but still no go.
