The Aster was chosen for Dutch schools by the Dutch ministry of education, in a set-up with eight disk-less Asters, and one Aster with high-capacity floppy drives all connected by a LAN based on the Aster's high-speed serial port hardware, and special cables that permitted that any single computer on the LAN could broadcast to all other computers. The floppy based system was operated by the teacher who could send programs from his floppy disk, and data, to the student's disk-less systems thanks to the special BIOS in those systems. The students could send programs and data back to the teacher through the same LAN, or could save to a cassette recorder built into the disk-less units. Through a special "video-switch" the teacher was also able to see a copy of each student's display on his own screen. About a thousand of such systems were sold for many hundreds of Dutch schools.
