Always interested in retro games and software.
I've thrown out all my retro PC hardware though as I can run anything I'm interested in with a VM, and modern hardware is just so powerful.
With a 4" square Intel NUC with Win10 I can run 3dFX EF2000 at 4k resolution using DosBox.
I use a similar machine running Linux for >90% of my hobby computing and that's what was used for the Open Watcom test.
The Watcom compiler works fine in DosBox, and all the non-DirectX Win32 samples I tried ran perfectly in Wine.
Any code editing or file handling is handled is done on the main OS though, and Microsoft's VS Code (oh, the irony) is a great free editor.

Anyway, I've waffled on enough probably because I don't want to admit that I haven't tried to set up the Blitz3D SDK.
Looks interesting, but a step too far right now.
