I have just got a few National Datacomputer DC4 systems and I was wondering
if anyone knows how to load software on to the system.

According to the web site its running NDOS and the "monitor" comes up when
you power it up. But for some reason it will not start to download porgrams
or any file for that matter.

Anyone have information on this system, user manual perhaps ?

Thank You,
