Talking To a Keyboard Controller

Goal: To have a single push-button (SPST) replicate multi-task keyboard functions. Example: I press a single PB, which tells the keyboard controller that I have (in likeness) pressed CTRL+SHITF+F2, in that particular order. The project: I need to duplicate specific keyboard actions (loops) with single push-buttons, and these actions must include the dealys that would occur from the keyboard. The concept, of course, is sending the correct sequence of HEX control codes to the clocked DATA line.


Thanks in advance for any help...

I would suggest a PIC (or other micro-controller) is by far your best solution - search the net for details of the codes sent by PC keyboads (not ASCII), and duplicate them in a PIC.

Thanks for the advice...I kinda was suspecting it would be the way to go. Well, it'll be a first for me; I've never touched a microcontroller.

Thanks for the links, too...seems like they'll be pretty helpful.
