Hi Bert,

Sure, go to this site and search for keyboard theory and interfacing in the PC hardware section.

Its a very informative site.

You will get many ready made codes to interface PC keyboard with 8051, but I would suggest try developing your own code after understanding how keyboards work and how KB BIOS in the PC works.

Good Luck

Simon
