To add, if it's using the Melzi board that some used, then you should be able to load g-code onto it using the micro SD card slot. It will depend on the firmware if it can recognise modern gcode though. You may be able to compile a modern version of marlin for it too.
There's some info about it here https://reprap.org/wiki/Mendel90
This is a very old printer, from the early days of reprap. From a practical standpoint you would get better results from the cheapest new ender i3, and it would be a lot easier.
If you want an interesting project though it should be entirely possible to get it working, and you'll learn a lot from it. If it's still using the original Sanguinololu controller board that will be your biggest issue, as I doubt a modern version of the marlin firmware will fit in a ATmega644P. Your best bet would be to replace the controller board with something modern, then you can use it as any modern 3d printer.
