ok, two questions. In at least the docs I have (11/45
service manual, user
manual, and handbook), I can't find a clear description of how to toggle a
program into memory.
I'm assuming that when you enter an address in the front panel switches
and
hit "load addrs", that the data lights
aren't supposed to automatically
show
the data value at that location. I'm assuming you
must hit "exam" first.
Is
this correct? If not, I'd be autoincrementing and
seeing the next data
value. Can someone give me a good example of just how to enter two or
three
words starting at a given location? I think I can
figure this out, but I'd
rather be sure so I don't skip over something that isn't working
correctly.
Second, since it's been over 20 years since I did any MACRO-11
programming,
could someone post a simple few line machine code
program I can enter and
run to see if the machine will even go into execute mode correctly. Maybe
something that just adds two constants and stores them in another memory
location.
Jay, I am going to post an email that Guy sent me when I was getting my
11/40 up and running. We can call it "PDP-11 program toggling for dummies"
