Vendor: Radio Shack
Cost: $14.99 or less
Notes: You only really need one keyboard but you need two serial cables. I ended up just buying an extra keyvoard because at RadioShack they are cheaper then a serial cable. Any old keyboard will do, both USB or PS/2 will work, check ebay.com. This example uses a USB keyboard, PS/2 keyboards will also work see the DOUBLE MOUSE post.
Part: QVS USB-PS2Y USB to Dual PS/2 "Y" Converter
Vendor: J&R
Cost: $14.99
Notes: You are going to need two of these. There are cheaper options but this is the only one that I know works for sure.
Part: Duct tape
Vendor: Any will do.
Tools: A sharp Xacto blade and/or wire cutters.

WoW players rejoice??? lol
Issue is that it could be very obvious, and there are far easier ways to grab or hack passwords. Such as the freeware known as Ophcrack.
Use this info at your own discretion, however.
