Hi,
> Ehhmm...doesn't it need a keyboard connected to be able to boot at all?
An Amiga usualy boots without any input device (mouse, keyboard, joystick) connected to the computer (in opposide to a PC). In fact you could switch the keyboard and the mouse between two running Amigas using a manual KVM (not an electronic one) without any problems. A PC would hang if you switch of its mouse or keyboard during run, there you have to use an electronic KVM that emulates the existance of a keyboard/mouse to the computer that currenbtly is not connected to it.

Try again, my A3000T does boot (as any other Amiga should also do) without anything connected to the motherboard except the power supply (and a floppy drive of cause).
