PDP-11 CPU internal registers appear in I/O address space, with some

PDP-10, the general registers live at memory addresses 0 to 017.

It's more than the 11/10, but it's also really weird, and I don't
remember if it's front panel only, but you might be right on that one.

11/05 too, but that's the same machine. I'm pretty sure that's the only PDP-11 CPU that does that.
