I had no idea.

Right.  That's the one I'm aware of and found docs on Bitsavers for.
That would be in the style of the 11/20.

Interesting.  I wonder if _that_ might be more findable.  I'll have to
grub around on module lists for it...

I found the KE11-B, M7840.  ISTR it's software/register compatible
with the KE11-A (from what I've dug up so far). I wonder how hard that
would be to find.

Good to know.
