A2000 Revision 4 - Amigakit?

[Oldsmobile_Mike]

Um, guys? The rev 4 German model A board *can't* be upgraded to a higher revision (short of replacing it completely). The model B rev 4 is a completely different design.

I knew about the Agnus with the German design, but none of the other mods people have suggested are applicable, either?  D'oh!!  :lol: :lol:

I still believe my "mod" is feasible using elements from quantum mechanics once the Compton Effect is neutralized; it merely requires a paradigm shift from 4 dimensions to 6, provided the Theory of Relativity can be used without regard to mass.

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

 Let's take a look inside Dan's brain.... shall we?

Trippy.

If you pay for the shipping...

There used to be a C64 program called, "FTOUWSM."  anyone remember it?

Stood for "Those of us who smoke marijuana"

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?

I'm telling ya, they didn't, man.  What possible use could more than three pins serve?  That's why I linked to the picture way back in my first comment.  Just Google search pictures of your motherboard.  It appears that C= Germany, in their infinite wisdom, provided two different sets of pin holes for two different types of batteries.  The question was, does the AmigaKit battery adapter not match up with either of these two sets of holes?

Here's a couple more pictures for you that I google searched.  You can clearly see that there's two different types of batteries installed - one using the lower holes, one using the upper holes.  But I'll eat my hat if you can find a picture of an A2000 motherboard with all six freaking battery pins all connected.

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?

[Oldsmobile_Mike]

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.

[danbeaver]

Your yellow line denotes the connection of the (+) terminal end -- 2 legged side.

Just a side thought, but you should be able to just "plug it in" (or probably honestly you could just press the battery into it's holes, just for a temporary connection), and measure the voltage at the pin on the clock chip or at the resistor with a multimeter.  I had to do this on mine (had some issues with battery damage).  Granted I haven't looked at the specs at all, but I assume at least the clock chip is the same on the German motherboard as on the standard?  Purpose of this test is to verify that you're getting voltage at the correct location.  Good luck!
