Quarantine seems to give generous time for experimentation. Like this computer engineer who ran MS-DOS 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 data.
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 turntable spins and reads an analog enrollment of a small RAM unit, which is 64K in size. Contains a FreeDOS kernel, modified by Bogin to reduce bulk, a micro variant of COMMAND.COM, and an updated version of INTERLNK, which allows porting files 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!!
