Parallel keyboard interfacing

Hello, all:

        I was browsing the Mini-ITX motherboard site recently
( and was intrigued by some of the cloaked "classic"
PC projects. The Mini-ITX is an extremely small form-factor PC motherboard
and this site outlines people's homebrewed projects.

        Anyway, there's a project using an Atari 800, a Commodore 64 and a
Commodore SX-64. This got me to thinking. In these projects the keyboard is
left in the case as a prop (non-working). I was thinking about using a
busted Amiga 500 (more internal space to mount stuff) for a project but I
want to find out how hard it would be to make the prototype keyboard
"working" by connecting it to a hacked PS/2 keyboard controller.

        Does anyone have a schematic for an actual PS/2 or AT keyboard? How
are the keys connected to the keyboard controller?

        Thanks in advance.
