Depends on whether the signal is active-low or active-high.

Yeah, it would... to be able to use it, there would have to be enough
Q/CD slots to have the main processor, then the KA650 and its memory.
With an 11/83 and 4mb, that leaves no slots in a BA23. Even if I
cut back to one 2mb memory board, that only leaves one slot, which
the CPU would occupy, with no room for a memory board for it...

I went looking yesterday and found my KA650 CPU module Technical manual,
so they do exist... EK-KA650-UG
