SIMH has worked on MS-DOS for a long while now... Just think of it as 'OS/2' ... :)
a 'direct' link to download it is here: http://sourceforge.net/projects/simh/files/simh%20binaries/3-8.1/simh-3.8-1_MS-DOSi386-exe.zip/download The only 'catch' of course is that anyone hoping for massive files or networking is currently out of luck.... I started looking at interfacing with packet drivers, but seeing that they run in real mode, and all the context switching involved just seemed silly... Unlike the other binary versions though, I put in as many os's as I could figure out how to run in a small state so that I could not only test the emulators but seeing how everything out there has some facility to run MS-DOS applications, it could be a 'lowest common denominator'... Although running emulators in emulators really kills performance, but in this day & age with 3+GHZ cpu's.... is it that bad? I built them with Watcom C++ 11, I'm sure I could have used something like Visual C++ 2.0 and bound them with HX DOS ( http://www.japheth.de/HX.html it's like Pharlap TNT, but free!), but I didn't see any easy facility for calling DPMI/MS-DOS interrupts so I just didn't bother.......... I would suppose you could take any BSD/Linux and make it boot into single user mode, with /bin/sh /bin/ls a populated /dev tree, and go from there to see about running SIMH, I've been playing with 386 BSD lately and it sure could run from a single diskette back then... I know the super cut down can be done...... but they always feel so limited... :) On Tue, Dec 7, 2010 at 10:02 AM, Bob Armstrong <[email protected]> wrote: >>Zane Healy ([email protected]) wrote: >> >>I used to have a dedicated box for PDP-10 emulation, it was built >>using a Celeron 500Mhz CPU. > > In a slightly different but related question - assuming you want to set up > a PC just for the purpose of running simh, what's the lightest weight > operating system that you can run on the host?
