M (non +) runs great on F11-based systems anyway. I don't know (remember) what I might have said. But depending on different things, running M+ on an 11/23 or 11/24 can be a little painful. But running 11M in general is more painful than M+ anyway, so I would at least recommend trying M+. Well, I have a personal desire to run M...I ran it for many years 25-30 years ago, and I like it. I've never had much experience with M+. I will definitely run M+ on the machines I have that are capable of running it, though. M+ is really nothing strange if you're used to 11M. It is just much nicer, more capable, and generally faster... ...and won't run on my 11/34, for example. ;) (I *think*...right?) Remember, while I do use simh quite a bit, I'm primarily based on real hardware here, and I can't do "set cpu .." on that. ;) (That said, without split I/D-space, you'll have preciously little pool space, but that might not be a big issue for you right here.) I think that was why. Yeah. Without supervisor mode and split I/D-space, you will have very little system pool. If you are not running a bunch of things on the system, you should still be able to survive though. Oh, and my TCP/IP will not work on those systems. THAT was it, I wanted to run your IP stack. I ended up setting it up (the OS, not yet your IP stack) on an 11/44 instead. Yeah. My IP will not run on such machines, and I have no plans on ever implementing it. It could be done, of course, but the work is no fun, and I have so many other more important things to waste my time on... :-) Well I'd be one user, if you ever decide to do it. I'd then bring up the world's first PDP-11/34-based web server! -Dave -- Dave McGuire, AK4HZ New Kensington, PA
