Message-ID: <20140518120538.2117118C0BA@mercury.lcs.mit.edu> Does anyone know if the source for an early PDP-11 version of MERT is available anywhere? (For those who aren't familiar with MERT, it was a micro-kernel [as we would name it now] which provided message-passing and [potentially shared] memory segments, intended for real-time applications; it supported several levels of protection, using the 'Supervisor' mode available in the 11/45 and 11/70. One set of supervisor processes provided a Unix environment; the combination was called UNIX/RT - hence my asking about it here.) Thanks! Noel
