I have a question, I revently found a old 3d printer in my brothers basement, apparently its a “nophead mendel 90” that he built years ago but then lost interest in.

I would love to try and bring it back to life, but I know very little about printing, and have no idea where to start. Is a printer this old compatible with modern slicers? What software would I use to connect to it via usb? I tried to do research on my own, but found very little useful info about how to actually get it working
