Right off I suspect yes. However is there any information on how
to "talk" software wise to them as to what kind of results and
commands they take?
It's all described in pretty decent detail in the PC AT Techref.
Look in the "System Board" section. When I first saw it, I wondered
why the IBM writers had wasted so much paper on it.
I don't have the PC AT Techref, any hope for that on line?
Also are the later versions (the AT version used a 8041A and the
386 and later versions use 8042 [more ram, more rom and faster])
the same as that spec?
