Computer keyboard with Playstation?

[js5895]

Hi,

Do you think it's possible to get a PS/2 computer keyboard to
work with a Playstation 2. Because I have an extra keyboard
collecting dust, and I would like to try to make it work.
I think the keyboard's chip has to be compatible though.
I only got it to light up, is this connection right:
ground-------------------+5
clock--------------------clock
PS/2 Keyboard data---------------------data Playstation 2 USB
+5-----------------------ground

Thanks.

If that what you say as "Playstation 2 USB" is really
an USB interface, the you definately got the pinout wrong.

The pinout of standard USB port is the following:
1 +5
2 -Data
3 +Data
4 GND

There are no separate pins for clock and data!

Well, I have a USB to PS/2 adapter, so I hooked it up the way the
adapter was hooked up, but in reverse.

Thanks.

This won't work. The keyboard chip _has_ to be able to speak both usb
and ps/2. A ps/2 keyboard can't speak USB, but many usb keyboards can
speak PS/2.
Buy a usb keyboard. It costs you 10$
