Avr program for Attiny 2313

Hi, I have a circuit that has an ATiny2313 IC on it, that is programmed with the attached program. (source code in attachment). It basically handles data from a PS/2 keyboard and records it on to a memory chip and also communicates with a bluetooth device. On the IC 11 pins are currently being used 9 pins are free. What I need is the program to be modified to re-program the IC so that another device can be attached via a Y cable and the data from that device also get recorded like the ps/2 keyboard. (note:- both the devices will always work one after the other, and never be used together. Hence there is no confusion of data, and just a simple Y cable is used, no need to have any special software to seperate the data) The other device that I wish to attach to the system. Is a panel of 12 switches. (each meant to write a character to the memory chip, when pressed) now I can modify the matrix circuit of these switches, But I need the IC to handle the simple switches and get them to work like a keypad and enter the data into the memory. I have a avr programmer to program the chip, so i will need you to be avaliable via Im for testing of your program. Any Questions? Let me know!
