there are a number of programs that will write a disk (floppy) in a pc.
but the old controls are limited to approx 11k max file size so big files have to be split down.
depending on what cam program you are using and what you want to make?
if doors etc panelcam
if art etc artcam
if other you have to use a file converter.
let me know what you make and il suggest something for you!
