My 11/34 is currently down awaiting replacement of an RK05 head which crashed rather painfully on Monday (the 13th !). In the meantime, I'm trying to sort out a new UNIX image for it, using an emulator on the PC. I have an 11/73 emulator for UNIX (Linux) with RK05s, and an 11/34 emulator (E11) for DOS, which looks great, but doesn't support RK05 yet. The 11/73 emulator runs the v5 and v6 images nicely. The question is, will these images run on a *real* 11/34 without a floating point board? The /73 and /34 MMUs are significantly different I believe. Looking at the v6 docs, the system is claimed to run on the 11/40, /45 and /70, but the /34 was yet to be created at that time, so there is no information about that! I'd be very grateful of someone could either tell me of a /34 emulator with RK05 image support, or confirm if v5/v6/v7 UNIX will run on: 11/34a 128Kw 1xRK05 no floating point no sep I+D (I guess) Cheers, Bob. -- ---------------------------------------------------------------------------- Robert Manners Osney Laboratory rjm(a)swift.eng.ox.ac.uk Dept of Engineering Science University of Oxford 01865 246561 x 162 Try: http://swift.eng.ox.ac.uk Linux - the only choice "There's more to life than books you know, but not much more" ----------------------------------------------------------------------------
