There are two models corresponding to the 85 and the 85B.
I am supposed to have an 9915B (that's what it says on the box), but the
main PCB says 9915-66512 Rev A. Go figure. If I could power it up I'd
know whether its an A or a B by the amount of RAM, but I am still debugging
the PSU.
As for the
control connector, I have no idea what that might be used for.
I don't recall if it's input and output or only input but the 9915 can
detect switch closures and take pre-programmed action.
