PS2/AT Keyboard Adaptor in Melbourne

[Fleetwood Mac Attack]

Hi,

I'm wondering if anyone knows of a shop in Melbourne, that sells an
adaptor that can plug a PS/2 male into an AT keyboard socket in a PC.

Or a shop that sells an AT cord gender switcher.

I'm basically trying to get a PS/2 KVM keyboard lead into an old PC
with an AT socket.

Thanks!!
