Computer BACKUP

Good morning everyone. I have a KBA Rapida 104 - 4 SW2. I would like to have another computer in case the one I currently have breaks down, but I am a bit lost. To set up this new computer, would I need a floppy disk with the MS-DOS system (Colortronic-system)? And a network card to communicate with the KBA 104 from the computer? Please correct me if I'm wrong. Where could I get these parts? Thank you very much everyone.

 

Hello there,
This is a very old computer system, to set up a similar computer (compatible with KBA 104) you must have the MS-DOS system, install it, and then install the machine program from the given floppy (every machine has its configuration). If you need the same used computer, I can arrange one for you, it was dismantled from 104 machines.
