Inbro 1201C II need help!

I recently acquired an Inbro 1201C II machine, but it isn't complete. It has no manual and also the original floppy disk is missing. Does anyone know where I can get these? I have not found a website with manuals or software so far.

I read on another thread that you can get rid of the floppy drive by using an USB emulator. Is it also possible to hook up a pc to this particular machine?

Also the screen is broken on this machine. I've found some 'new' replacements on ebay, but would it be possible to use another monitor instead? I've seen a serial port and I was wondering what it was for and if I could use it to put a monitor on it.

I hope someone can help me with my questions.
