r/DOS

I was trying to understand the code of MSDOS-1.0, as released by Microsoft. But my understanding of i86 Assembler is a bit rusty, so I thought: "What about reading the code in C?". I also thought it could be a good check of the capabilities of LLMs and OpenCode... so I gave it a try. This is the result, which I'm finding quite interesting for educational purposes...

Why did Microsoft open-source MS-DOS 1.25, 2.0 and 4.0 but not 3.x?

I mean 3.x came out after 2.0 and before 4.0. So why did they skip a version?

Best DOS Gaming PC?

Would I be better off getting a 386/486 DOS PC over any of the Tandy 1000 seires PCs for 1980s DOS games? I am mostly interested in playing 1980s DOS games, but I am not sure if I should go with a bit newer hardware by getting an early 90s pc?
