Start MS-DOS from a vinyl record

Quarantine seems to give generous time for experimentation. Like this computer engineer who ran them from a vinyl record.

If you're old enough you'll no doubt remember the days when you loaded programs onto the Spectrum from a tape recorder. Since the beginnings of computers, sound has been a means of transmission .

The Slovak engineer Jozef Bogin in the midst of quarantine probably the terin. So what he did was boot into MS-DOS, but instead of using a traditional tape, he decided to try a vinyl record.

In the video below you will see in detail all the steps, but we should warn you that it is recommended to turn down the volume of your speakers, as the sounds that are heard are piercing. Users of 80's machines certainly know.

As you can see, MS-DOS does not boot on a modern , but on a prototype IBM 5150. The audio loading process is actually surprisingly fast as MS-DOS 6.22s are rather small in volume.

According to Bogin's website στον υπολογιστή υπάρχει ένας μικρός boot loader που χειρίζεται την ενσωματωμένη «διασύνδεση κασέτας» του υπολογιστή και που επικαλείται το BIOS εάν αποτύχουν όλες οι άλλες επιλογές εκκίνησης, π.χ. δισκέτα και disc.

The turntable spins and reads an analog record of a small RAM unit, which is 64K in size. Contains a FreeDOS kernel, modified by Bogin to reduce bulk, a micro par of COMMAND.COM and an updated version of INTERLNK, allowing file transfer via printer cable, modified to run in FreeDOS. The bootloader reads the disk image from the audio recording via the tape modem, loads it into memory and boots the system to it.

While this may sound like rocket science to some, it is actually an experiment that could keep you busy in quarantine. Of course, there is no benefit other than having fun with the software and the satisfaction of getting it done.

If you want to try it at home, Bogin gives all the instructions through his website. Good luck!!
