Hi, I have been reading through the turorial on Keyboard Controller Programming, and it says that the status byte is obtained by reading port 0x60. however, I have read elsewhere that it is obtained by reading 0x64. Which is correct?

The status register is indeed located at port 0x64. I am going to have to fix that..
Also, please note that there is no keyboard programming tutorial as of yet. Some information about the keyboard controller is provided in tutorial 9 for better understanding of the code.
Port 0x60 represents the keyboards input and output data buffers. Port 0x64 represents the keyboard controllers command and status register.
