thanks

what is the most powerful ps/2 or ibm aptiva and cpu that supports the latest version of os/2 out of the box with included drivers for vintage pc?

Last paragraph of the blog post covers modern OS/2. As for OS/2 drivers, I was always able to find drivers for all but the cheapest graphics cards, including 3D accelerators. Cheap sound cards, cheap network cards, and Winmodems could be problematic but those types of devices gave you trouble in Windows too.

BeOs has awesome demo

i’ve seen posts on forums on ibm os/2 complaining that they couldn’t find drivers or os/2 wouldn’t install on their pc.

i suppose i might add i’d like to have graphics and especially GUI accelerators supported. in the 90s there were 2d GUI accelerators like diamond viper whose sold purpose was to accelerate windows 3.1 redraw

are there any modern pc build that succeeds os/2

Most good quality AT standard clones, like Compaq, Zenith, etc, and of course IBM’s own ATs

I remember the guys from Microsoft turning up before “OS/2” giving us the skinny on “Advanced286Dos” because that’s what it was called (designed in the days when the 286 still held sway). The tricks the os had to perform to swap from one VM to another meant it was always going to be suboptimal on that, and then the 386 appeared.
When it was in full swing and we were implementing OS/2 drivers we all hoovered up Gordon Letwins book Inside OS/2, which I still have. It was a fine operating system but in and amongst the ubiquity of DOS, Xenix and the other Unix lookalikes, and the fact that ultimately Microsoft dumped it in favour of the next Windows it withered away. The other issue was that it’s networking system – Lan Manager – was not as fast as Novell, and as interconnectivity was starting to be a major thing that’s was no good.

Neither OS/2 nor BeOS had much native software available but OS/2 could run DOS and Windows apps. I liked them both but OS/2 was more practical to use.
