A2000 Revision 4 - Amigakit?

[Erol]

I have a coin battery I purchased from Amigakit.
Does anyone know if this will work on revision 4 boards?

Just I looked at this board and the pin layout and traces look different from later revisions of A2000.   I know these boards had varta batteries but are the pin layouts the same?

I have attached pics of my A2000 board.

Well that's unique!  Nice to see one in such good shape.

thank you for replying, the board is in mint condition.
i will do bit more digging on the net  im sure replacement varta batteries that dont leak should be available somewhere.
seems the coin batteries Amiga kit supply work fine on later revisions,   problem i have is the pin outs are further out and there more of them.

Maybe he wants to keep it all original?  Bugs and all?  :lol:

Thanks to everyone comments,  an interesting read.
Its crazy how many A2000 models they are,  more than any other Amiga.

I wont be using the A2000 extensively as I have an A3000 for anything more accelerated.
I would prefer to keep board unique and unchanged, but with a battery that isn't too obtrusive and working (leak proof).

Dan, when you dip off to the 6th Dimension, can I have all your Amiga's?  :lol:

I wonder what kind of Amiga would be in the 6th Dimension.  

so to clarify i'm still confused on the clock battery, the traces on the three points on the clock adapter don't seem to connect to any of the motherboard traces..  

there must be someone who has a revision 4 board whom can clarify if the original varta batteries had more than 3 pins?

The question was, does the AmigaKit battery adapter not match up with either of these two sets of holes?

I have to bend the pins a fair bit to get them aligned.
so my next question is, on all examples pics i have seen the battery is aligned with the markings BAT1 BAT2 and BAT3.
But if you look at my pic without the battery you can see there is no connecting traces  except to the holes above BAT1&2 and the small hole to the left of BAT3.

How does the board notice there a battery installed? if there no connecting traces to the rest of the board?

Two layer board, no traces on the bottom?

There one trace line going up on back of the board.. i have marked in yellow line.
it obviously stops at each hole in that line.
