TEOS - Commodore 64 char mode OS - Status #1

An old work in progress video. Showing desktop, files app and simple counting app. Launching, moving, minimizing, de-minimizing and closing. Has memory allocation on the heap for app and app screen backbuffer. "Loads" app from a ramdisk structure. Relocates app code after copying into heap memory. Each frame/refresh the focused app gets first called, then one non-focused "background" app (round robin). An app can trigger content repaint as needed after its update and all app repaints happen at the bottom of the screen and vertical retrace down to the visual area again on the top. App execution happens in the visible screen area.
