11/05 too, but that's the same machine. I'm pretty sure that's the
only PDP-11 CPU that does that.
I have a clear memory of playing with this, and I don't recall ever
playing much on an 11/10 or 11/05. I'm pretty sure it was on the 11/70...
Ah, yes. Checking the processor handbook, both the 11/44 and 11/70 have
the general registers at memory addresses for manipulating from the
front panel/console. Other do as well, but I'm not going to read through
all documentation right now.
(The 1979 processor handbook, page 329 shows it for the 11/70 anyway.)
So they do! Wow, I've never run across that.
You've probably not sat as much in front of a PDP-11/70 front panel as me...

Hello!
Well he does live with a good collection of them. Also a crowd of
frustrated Yeti and six snowmen.....
Gang can we put this aside and concentrate on what's what, and who's
who regarding the Port of NetBSD for the VAX?
