11/45 front panel question

Jay> ok, two questions. In at least the docs I have (11/45 service Jay> manual, user manual, and handbook), I can't find a clear Jay> description of how to toggle a program into memory. Jay> I'm assuming that when you enter an address in the front panel Jay> switches and hit "load addrs", that the data lights aren't Jay> supposed to automatically show the data value at that Jay> location. I'm assuming you must hit "exam" first. Is this Jay> correct? If not, I'd be autoincrementing and seeing the next Jay> data value. Can someone give me a good example of just how to Jay> enter two or three words starting at a given location? I think I Jay> can figure this out, but I'd rather be sure so I don't skip over Jay> something that isn't working correctly. The way it works is this: - Load address sets the address you're working from - Exam shows what's in the working address - Deposit changes the contents at the working address - If you do exam and exam again, then the second exam increments the working address first. - Ditto on deposit and deposit - However, exam then deposit don't change the working address So, for example - load address 1000 - exam exam exam shows you locations 1000, 1002, 1004, and - load address 1000 - exam - deposit 20 looks at location 1000, then changes location 1000 (NOT 1002) to 20. Jay> Second, since it's been over 20 years since I did any MACRO-11 Jay> programming, could someone post a simple few line machine code Jay> program I can enter and run to see if the machine will even go Jay> into execute mode correctly. Maybe something that just adds two Jay> constants and stores them in another memory location. Here's a lovely hack -- a one instruction program. Load it at the last location of your memory. For example, in a machine with 28 kW or more, load it into 157776. The instruction word is 014747. Deposit it and start it. If the machine is working right, you'll end up with 014747 in all your memory from 157776 down to zero. An exercise for the student is why this is so. paul
