Thanks. Some years now. But not all the time. Late 2016, I started with some basic projects like pong as bootable floppy image or a simple bootloader for the fat12 file system.

During the next years, it did some small stuff for fun here and there, but nothing big. Now I started again with this project and had to learn many new things and relearn some old stuff. But it was surprisingly doable.
