DOS/BATCH? That would be DOS 8 or later. I don't know if that still supported the RC11. I do know for a fact that DOS 4 supports the RC11, that's what our physics department machine ran initially. RT11 doesn't support RC11 out of the box, but adding that isn't all that hard. I wrote a driver for it in college, and another (independently developed) one was released at some point by someone from DEC and can be found online. You have to add a boot driver also, of course. RSTS supported RC11 for some time, certainly in V4 and probably a bit longer, but only as a disk for swapping and OS overlays, not to hold a file system. paul
