If you are still looking for the A3000, I have one.
I only need to shoot some photos and a short video to demonstrate the machine working.
The battery has already been replaced with a coin cell one, and the board has been cleaned before of course. The computer works perfectly fine.
The only thing that I didn't have the time to fix is the power LED which doesn't light up for some reason.The HDD LED works fine instead.
The computer has 2 MB chip and 8 MB Fast. There is a SCSI HDD (the original one I guess).
Kickstart has been updated with 3.1, so there is no need for the SuperKickstart floppy disk (although I have it original).
Ramsey, DMAC and Buster have also been replaced with more recent ones.
