Good morning Robert! I sent an e-mail to the address you have on your github.

In case anyone is interested in trying MMURTL, I added a couple bootable floppy .img files in the images directory on the repo.

mmurtl.img – Boots to PC-MOS/386 then use mmloader.exe to launch
or use mmlaunch.bat from the root of the drive.
mmurtlsa.img – Standalone MMURTL bootable floppy. Custom boot
loader launches MMURTL natively.

If you run it in VirtualBox, be sure to use IDE disks. If you set it up as a DOS VM, it should be ok.

If you run it on bare metal, be sure to have your disk(s) configured for legacy IDE compatibility. MMURTL doesn’t currently support SATA, so you will need to emulate IDE or it will complain it can’t find anything after you boot it up.

Part of me wants to convert as much as possible to GCC & GAS, although I really should be messing more with the NE2k and Mach along with trying to find and fix more of libc to have a real standalone 4.3BSD on i386……..

I never managed to work through it, coming from a 68k and Unix background the PC architecture (and, probably, the structure of MMURTL) was simply too strange.

Back then in the 90’s, Comer’s original Xinu book (the PDP11 edition) seemed much more accessible to me and I still love to use parts of it in my OS courses.

But it’s great to see that the MMURTL book and code are now freely available, maybe it’s time to check it out again…
