These functions:
1. Are undocumented and are only there for DOS virtual machine
backwards compatibility?
2. Have to be called from the kernel, you still need to write a device
driver and delphi is not a good tool for device drivers!
3. Open an incredible security hole, so are undesirable!
4. If you are still trying to access port 60 you have the problem the
keyboard driver owns it so you shouldn't be accessing it.
Get a clue!

And it will still crash since you don't own port 60! Tell this list in
general terms what you think you are going to accomplish by hitting port 60,
and we may be able to give you a valid approach to getting there.

is the keyboard special? if it is not special, the ps2 driver will handle
the device just fine.

NT is a real operating system 
. Unlike win9x, it doesn't allow any direct
hw access from any process.

You have a misconception. You assume that Win95, Win98 and WinME are
operating systems, when their primary task was to simply function as a
wrapper for DOS. NT, 2000, 2003, and XP provide strong separation of user
and kernel functions, hence you cannot "steal" someone else's hardware
without dire consequences.
How many more times must you be told NO?
