Hi,
    I'm trying to get an AT keyboard to communicate with my PIC16F84 and I'm
having a great deal of trouble with it. The PIC is running at 4MHz and I'm
using a modified version of Adam Chapweske's code (I made a few identifiers
uppercase instead of lowercase) and I'm getting the following data from my
BTC 8140M keyboard (AT-style, supposedly ergonomically designed, has a nice
Synaptics Touchpad fitted, too), all data in hexadecimal format. The
keyboard was connected to a Cuecat's pass-through connector, then the 'Cat
was hooked up to the MiniDIN port on my protoboard:
On power up:
    AA     Selftest passed
When the "1" key is pressed:
    56     "1" scancode with bit 6 on (WTF?)
    FA     Unknown
    FE     "Resend"?!?! But I didn't send anything to the keyboard...

Have I missed something here?

Thanks.
