AFAIK the ideas are the same as the same signals (VCC, KBCLOCK, KBDATA, GND)
suggests. The only problem is that they are differently implemented. They may
differ in various ways. Logic, timing, frequencies etc. And of course the
keycodes. In what exact way(s) they do differ I can't say as I don't know
enough about the pc keyboards.

And that's the problem due to the reasons mentioned above.
