Tom,
don't type the line numbers from that Web page. You simply want to
"open" one location at a time (do this by entering the address in octal,
followed by a forward slash, no spaces anywhere), and after ODT has
displayed the (in this case meaningless) previous contents of the memory
word, you want to replace it with the appropriate octal value. Replacing
and opening the next location in sequence can be done in one step by
using the "line feed" key instead of "return". If your keyboard has no
key labelled "line feed", Control-J should do instead.
When done, you start the program by entering the start address (1000 in
this case) and typing G (for "go"). I believe setting up the status
register and stack pointer, as mentioned in the comment at the top of
the listing is more cautious than you need to be here.
The procedure would then look like this (the <LF> means press "line
feed", <CR> means the return key):
173326
_at_1000/XXXXXX 12700<LF>
1002/XXXXXX 100240<LF>
1004/XXXXXX 12701<LF>
1006/XXXXXX 177170<LF>
... yada yada yada...
1132/XXXXXX 0<LF>
1134/XXXXXX 5007<CR>
_at_1000G
Hopefully, you will see your RT-11 booting here. If not, you have most
probably mutated the program by spotting one of these digits wrong. If
it is not yet overwritten, you can go back from the _at_ prompt by entering
the address again, followed by the slash, e.g.:
...
1004/XXXXXX 17201<LF> <- typo, two digits reversed
1006/XXXXXX <CR> <- press return to exit
_at_1004/017201 12701<LF> <- open location 1004 again, enter corrected
value
1006/XXXXXX 177170<LF> <- continue entering code
...
