I'm not sure on the monitor - I have a PS/2 monitor that goes with it but it's not even close to functional. I found lots of pine needles and rust inside when I opened it so I'm guessing it sat outside in the rain for a period of time.

My PS/2 did not come with any disk, nor does the disk drive spin or turn on its activity light. As far as I can tell, the power supply appears to work fine. I tried hooking a bench top DC supply in place of the battery and it made no difference.
