In this directory, and different subdirectories are programs related to the DEC pdp11. This area will probably get more organized sometime in the future. For more information, ask Johnny Billquist (bqt@update.uu.se) doc contains different documentation. Some of it has been snatched from usenet news, other stuff has been sent to me. emulators contains different emulators that emulate the pdp11 for different other hardware. pos is a pointer to the professional directory, since this machine normally runs P/OS. (I know there are other stuff as well...) rsts contains stuff specific for RSTS/E. rsx contains stuff specific for RSX-11. rt contains stuff specific for RT-11. xinu contains stuff for the xinu operating system. k11mit.tar.Z is the k11 files from watsun.cc.columbia.edu pdp-gcc.shar is a pdp-11 backend to gcc. It was copied from mike@vlsivie.tuwien.ac.at (Michael Gschwind). Maybe he can give answers to questions. I can't. decusc.tar.Z was sent to me from Mike Young. I think it has some fixes not in the official distribution from DECUS, but you would be better off asking Mike yourself. Also, he has DECUS-C available by ftp himself, and that copy is at least as good as this one (probably better). teco11.tar.Z is teco-11 V39. Some of the stuff is definitely for VMS, but it seems to be meant for all different pdp-11 OSes as well. I'm not sure this is a complete distr. The setup isn't 100% strict. Some DECUS software that has been distributed for one OS really works on others as well, but are still placed only in one directory, so browsing around can pay off. And... NEW CONTRIBUTIONS ARE ALWAYS WELCOME!
