Well I've managed to find some Fortran installation instructions here:<br><br><a href="http://www.bitsavers.org/pdf/dec/pdp11/rt11/v4.0_Mar80/4_fortran/AA-5240D-TC_RT-11_FORTRAN_IV_Installation_Guide_May79.pdf">http://www.bitsavers.org/pdf/dec/pdp11/rt11/v4.0_Mar80/4_fortran/AA-5240D-TC_RT-11_FORTRAN_IV_Installation_Guide_May79.pdf</a><br>
<br>Thankfully google seems to OCR these things, otherwise I'd have never found it.<br><br>I've managed to install "Fortran IV V02.1 Compiler Files" and the "Fortran IV V02.1 Objecttime System"<br>
<br><a href="http://www.headcrashers.org/comp/rx01/fortran-iv/fortran-iv-v021-compiler-files.img">http://www.headcrashers.org/comp/rx01/fortran-iv/fortran-iv-v021-compiler-files.img</a><br><a href="http://www.headcrashers.org/comp/rx01/fortran-iv/fortran-iv-v021-objecttime-system.img">http://www.headcrashers.org/comp/rx01/fortran-iv/fortran-iv-v021-objecttime-system.img</a><br>
<br>building demo.for works, so I thought I was almost there...<br><br>I've managed to build & link either <br><br><a href="http://www.pdp11.co.uk/library/local/pdp-11/RT-11/dungeon1.dsk">http://www.pdp11.co.uk/library/local/pdp-11/RT-11/dungeon1.dsk</a><br>
<a href="http://www.pdp11.co.uk/library/local/pdp-11/RT-11/dungeon2.dsk">http://www.pdp11.co.uk/library/local/pdp-11/RT-11/dungeon2.dsk</a><br><br>OR<br><br><a href="http://www.ibiblio.org/pub/academic/computer-science/history/pdp-11/rt/dsk/misc/dunsrc.dsk">http://www.ibiblio.org/pub/academic/computer-science/history/pdp-11/rt/dsk/misc/dunsrc.dsk</a><br>
<br>however neither dungeo.sav that is created will run, it doesn't generate any errors or anything...<br><br>I thought it may be running under the wrong monitor as I've been using the v4 image from the software kits:<br>
<br><a href="http://simh.trailing-edge.com/kits/rt11swre.tar.Z">http://simh.trailing-edge.com/kits/rt11swre.tar.Z</a><br><br>however the binary that I've found here:<br><br><a href="http://www.geocities.com/capecanaveral/5517/dung.zip">http://www.geocities.com/capecanaveral/5517/dung.zip</a><br>
<br>works fine..  So I'm at another impass...  Was dungeon this difficult to build back in the early 80's??<br>
