Graphtec CE3000-60 hack?

Hi All,
I was gifted an old vinyl plotter that does not run on modern tech. It does operate just fine however. I was wondering if someone has some tips or resources for hijacking it. Such as, how would i go about communicating with it via my Pi4 or even Mac (OSX).

Is it possible to put in a new processing board entirely? My goal is to convert it to a draw bot or just update it so i can use it.

Any tips or suggestions would be great. I can supply photos of the unit if that helps.

\thanks!

Interesting question but impossible to answer with the information you have given. What make and model is it, would be good to start with. Photo might help!
