In the last blog-post I discussed developing retro-apps for Windows that can be run under OS/2 using the WLO toolset from Microsoft. But what about native coding under OS/2 directly?

Retrocomputing with real hardware is a very nice way to understand how modern computers have learned to run and talk. I developed some GUI for OS/2 Warp 3.0 and Windows 3.11 to control some of my microcontroller-projects.
