Optimize retro coding on Apple Silicon MacBooks using OpenWatcom 2.0 for DOS/OS/2 development. Install Xcode, homebrew, DOSBox for smooth compilation

I recently found a 386 emulator called 86Box, a fork of the earlier version of PCEm. Because I'm a real programmer™, I build the master branch from its Git source on a macOS Ventura. How I build it from sources will be the subject of a new article. B...

You might find the title a little bit odd. Hold your thought for a moment and hear me out. I'm a big believer that in technology, and life, something that comes from consensus from a big, top-down standardisation body usually fails. The internet is a...

In my articles in this retrocoding.net I use OpenWatcom compiler extensively. This is because this is the only compiler which allows me to program back into the ancient world. By ancient, I meant, the world of 8088, where the first PC was made. I exp...

Integrating mbedTLS and patching it to be compiled on OpenWatcom so it can run on Windows 95 and intel 486 retro computer

This second article is an continuation of my first article about building a simple HTTP client which runs on Windows 2000 onwards. Before going backward to the like of Windows 9x, Me, and NT 4.0 we're going lateral first. We'd try to make our code w...

Goal TLS 1.3 has been defined in 2018 and it has been 4 years from the definition, and earlier version TLS 1.2 has been defined one decade earlier at 2008. TLS 1.2 supports on Windows started from Windows 8.1 and Windows 7 Service Pack 1. If you want...

So I've written about how to do Hello World in Linux and macOS. You might need to check it out. Toolchain For this article, I will still use GNU Assembler as our tool of choice. We'll be using MINGW-W64 to build our hello world project. MingW is a G...

I want to start this blog with something that's easier to digest and maybe relevant with the theme of this blog: Assembly. It's 2022 and we're thinking: can I program in assembly nowadays? Well it turns out you can. Assembly is pretty much alive not ...
