I seem to recall that I used Windows 2 on a RM Nimbus 80186 at school around 1984. It was for CAM.
Nowadays one of my customers has a sodding great machine that boots DOS 6. To get data files to and from it I use Samba with all the safety catches switched off (on one side only) as a go between.
Nimbus was another one of these "DOS Compatible" kinda-IBMish things that you could get a lot of stuff to work on. It must have had at least CGA compatibility because of all the DOS games that would work. It was the first machine I must have used Windows 2.0 on, but I barely touched Windows before 3.0.
