I own a (very) old Gravograph VX89 graving machine.
Lately, my floppy disk that I use to start the program of the machine with stopped working and therefore the machine is not able to work now.
I contact the importer of the machine but he of course told me that he doesn't support this machince anymore.
Does anyone knows what can I do? The software version, as far as I know, is PRH 06.20.
Is there any place that I can buy that disk? Any suggestions what so ever?

Any help would be appreciated, thank you guys!
