You mean, analogous to CDC's PPUs? One guess:
that wasn't an option
on the PDP-6, and the 10 is the compatible successor to the 6.
Yes, good example.
I do not think adding some sort of -8 powered channel stuff to the KA
would have disrupted things much at all - there just was not a huge number
of PDP-6 installations to disrupt. Likewise, they could have included
backwards compatibility.
