1200XL KEYBOARD TO 400/800 MODIFICATION


  • To modify a 1200XL keyboard to work on other models of Atari computers remove the 15 conductor cable, ic chips, capacitors and resistors from the board and connect wires from the 22pin keyboard connector in the computer to the locations shown in the following diagram. I have done this modification to a 400 and think it will work with all models. I believe that the programmable function keys should operate properly on XL/XE computers but the OS in the 400/800 does not recognise them.
