DR-DOS

[Liam Proven]

Might be more helpful to include downloads!

I'm still working on VMs, but I know have bootable diskette images of
both. To the best of my knowledge, this is the first time either has
been made available.

DR-DOS 7.08 is here:

You'll need the rest of DR-DOS 7.01 to install a complete OS but
that's widely available.

A bootable PC DOS 7.1 diskette image is here:

https://www.dropbox.com/s/zsujtvp0gs44qcx/PCDOS71.vfd?dl=0

This is a VirtualBox disk image, containing the PC-DOS 7.1 files from
the IBM ServerGuide Scripting Toolkit, as made available by IBM and
described here:

If you get that first, AIUI that gives you a licence to a personal-use
copy. I have not modified these files in any way except to combine the
separately-downloadable files and the boot disk image, and to remove
any non-PC DOS files from the disk image.

Again, the rest of the OS must be taken from a copy of PC DOS 7.01.
That too is widely available.

Feedback welcomed.
