Classic MacOS included in its kernel graphical functions and even the GUI toolkit and widgets. For example, there are DOS kernel functions available by system call for character mode input and output… but if you want to do anything graphical, you have to go straight to the hardware from your application. There’s lots of variations in the functionality operating systems can provide to applications written to run on them. Grub can do a lot of things, but it doesn’t provide any system services to applications or even run at the same time applications are running, and that’s why it’s not an operating system. MS-DOS, classic MacOS, macOS, Linux, Windows NT, and yes even Windows 3.1, all do this and that’s why they are operating systems. This is a call that is usually mediated by a system runtime library which calls into the operating system kernel, and the operating system code runs to perform some privileged or system action on behalf of the application. I think we’re missing a big part of the definition of “operating system”, in that an operating system runs its applications while also staying loaded, and that it provides some core functionality and services to those applications.Īn application that needs to open a file or terminate itself or lots of other “system” things, will make a “system call”. Posted in Misc Hacks Tagged ESP32, FabGL, IBM PC, pc Post navigation If you remember name, it’s probably from his excellent FabGL library. We’ve seen the ESP32 emulate 8-bit gaming systems before, too.

It’s a testament to the capability of modern microcontrollers that this is such a simple feat in 2021. It’s amazingly complete, with the ESP32 handling everything from audio and video to sound output and keyboard and mouse inputs. The latter game was actually considered somewhat of a de facto standard for PC compatibility in the 1980s, so the fact that the ESP32 can run it with code suggests he’s done well. There’s QBASIC, FreeDOS, Windows 3.0, and yes, of course, Flight Simulator. The full playlist is quite something to watch, showing off a huge number of old-school PC applications and games running on the platform. That’s thanks to work from, who has shared a how-to on Youtube. Once heavy, cumbersome and power thirsty, it’s a machine that you can now emulate on a single board with a cheap commodity microcontroller. The IBM PC spawned the basic architecture that grew into the dominant Wintel platform we know today.
