I recieved a call from my friend that were the winner of the first ebay auction on this A3500.
So he would like to compare this A3500 with mine, as he know that I have a real unit even with the A3500 draft manual ;p)
So the motherboard of the ebay auction one is a real A3500 REV II (the green PCB one).
But the A3500 were built into the Commodore PC 60 Tower (the high end commodore pc server).
On the backside of this selling unit there is a commodore A3000T silver sticker with model name, voltage input, FCC regulation, and stuff like that. So the A3000T was made after the the A3500. So it's impossible that it's the motherboard original casing.
So the tower is a real A3000T one with a Commodore PC 60 front pannel.
The Original A3500 doesn't wear this C= Silver sticker as it wasn't supposed to be sold to public.
Now the seller add the comment not an original Commodore front label sticker on its auction comment.
I don't think that the seller is a liar, he probably baught this machine like that years ago.
Anyway I'm wishing good luck with this auction.
