(Heinz mentioned that it had been done before.) On thinking about it, I might do the -11/03 port of Mini-Unix for the hack value; it looks like it should be a quick project (a couple of hours, much of which would be getting Mini-Unix set up; I'd use a simulator, my QBUS RK11 emulator is broken at the moment). I think it should mostly just be some fairly straight-forward changes to mch.s; I think all the C code would be fine. (Unless there's an 'PS->integ' or something hiding somewhere.) Also a few odds and ends, like a software console switch register (been there, done that). That would make the full power of Mini-Unix available to people with -11/03's; those are still fairly common, and reasonably cheap. (Unlike -11/05's.) It's a considerably more capable system than LSX: e.g. the tty driver is the full V6 one, and supports an arbitrary number of devices. So my question is: had anyone else already done this (I don't want to waste time replicating already-done work)? Also, would anyone have a use for it if I did it? If so, I'll put it up on a Web page when I'm done. (No, I _don't_ use Guthub, and have zero interest in learning how. I'd rather spend my remaining un-comitted neurons improving my ability to read feudal Japanese.) Noel
