I have been able to get through a lot more of the simulator-equivalent processing steps to match the input of the bootstrap programs where I to be working on the actual system using a Flexowriter. I have been able to answer a lot of my earlier questions via trial and error, and a lot of reading. I believe that loading the bootstrap manually is a must; one cannot use or create tapes otherwise. I don't think this SIMH has the bootstrap pre-loaded.
In order to enter instructions into memory I learned how to translate code from the various actual papertape sources... "flexowriter entry"> 6300 P 0000' becomes sim> d -a 6300 10000000 where 6300 = memory loc in drum memory, 1000 = P, 0000 = accumulator address (?). You can't store a "P" or "p" in memory. You have to convert to its Flexo binary equiv. ...it's slow going and I have been patching together what I think would be a workable bootstrap install process, but I expect to have to try a number of variations before I get any response from the machine. Who knows, maybe I will be able to contribute a software guide from all of this. I will document what I find and post on my web site, vintagecomputer.net. I am going to post this onto classic cmp, sorry about the cross post email. Bill
