Wer das Video schaut, sollte besser vorher den Sound etwas runter drehen. Ist ne echte Zumutung für die Ohren :) Mehr Infos zum Vorgang hier.

The turntable spins an analog recording of a small bootable read-only RAM drive, which is 64K in size. This contains a FreeDOS kernel, modified by me to cram it into the memory constraint, a micro variant of COMMAND.COM and a patched version of INTERLNK, that allows file transfer through a printer cable, modified to be runnable on FreeDOS. The bootloader reads the disk image from the audio recording through the cassette modem, loads it to memory and boots the system on it. Simple huh?
