That's correct. Now, the interesting thing is
that according to pinout
charts, the keyboard cables are the same (clock, data, not used, ground,
+5). However, the keyboards are not compatible. Does anyone know what
the difference is?
Off the top of my head it might have something to do with the layout of the
keys, and a different number of keys.
Different microcontrollers. Completely different protocol.
I do know that they are
incompatible, although you can get a device to allow you to connect a PC
Keyboard, I believe it costs about as much to get the adapter as it would
to get a keyboard (go figure).
There are a couple of quick-n-dirty hacks out on Aminet
(
wuarchive.wustl.edu/~aminet). I am not aware of any pre-made adapters which
are significantly cheaper than $50USD.
