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... ;-)
Probably not. ;) I run it whenever I can, but my only front-panel interaction with it is booting and demonstrating the toggling-in of simple programs to visitors...never any actual debugging.
