Dear Forum Members,
I want to interface the PCAT Keyboard to P89C51RD2HBP.
I have searched the 8052.com, for PCAT Interface, implemented the Application note found in this search. This is an excellent routine, and my keyboard was up in no time.
Using this application note I can use the regular keys, But I want to implement Ctrl, Alt, Function Keys, INSERT, DELETE, HOME keys etc. also. I also want to implement the Caps Lock, Scroll Lock and NumLock Functions also. i.e. I want to give the full keyboard functionality to my product.
Can anybody give me some information on how to implement this?

Thanks to all,
*********** HAPPY DIWALI ******************
