Thanks, that brings back soooo many good memories!
I wish there would still an easy way for kids to do similar graphics programming on modern PCs. Back then it was very easy to bring pixels to the screen, you just needed a few lines of code to switch to the correct mode. But nowadays with Direct X / Open GL you have layers and layers of abstractions between you and the pixels. And "setting up"Turbo pascal is still way easier than a modern Visual Studio.
I wish there would be some sort of modern Turbo Pascal which lets you do similar programming by faking / emulating the whole VESA stuff.
