It seems that quarantine is generously allowing time for experimentation. As in this mechanic computers which ran MS-DOS from a vinyl record.
If you're old enough you'll surely remember the days of preloading with nostalgialetterthem to the Spectrum through a tape recorder. Since the beginning of computers, sound has been a means of data transmission.
Slovak engineer Jozef Bogin in quarantine probably ended it. So what he did was start MS-DOS, but instead of using a traditional cassette, 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 computer, but on a prototype IBM 5150. The audio loading process is really surprisingly fast as MS-DOS 6.22 is rather small in volume.
According to Bogin's website the computer has a small ROM boot loader that handles the computer's built-in "cassette interface" and is invoked by the BIOS if all other options failmovements, e.g. floppy disk and hard drive.
The record player spins and plays a small analog recording unitς RAM, η οποία έχει μέγεθος 64K. Περιέχει έναν πυρήνα FreeDOS, τροποποιημένο από τον Bogin για να μειώσει τον όγκο, μια μικρο παραλλαγή του COMMAND.COM και μια ενημερωμένη έκδοση του INTERLNK, που επιτρέπει τη μεταφορά αρχείων μέσω καλωδίου εκτυπωτή, τροποποιημένη ώστε να μπορεί να εκτελεστεί στο FreeDOS. Ο bootloader διαβάζει την εικόνα του δίσκου από την εγγραφή ήχου μέσω του μόντεμ κασέτας, το φορτώνει στη μνήμη και εκκινεί το σύστημα σε αυτό.
While this may all sound like rocket science to some, it's actually an experiment that could keep you busy in the midst of quarantine. Of course, there is no benefit, except perhaps from the fun of playing 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!!
