to teach students.
there are four tape punchers (?) for djs -130 computer.
the djs-130 only has 32kb memory and 10mb hard drive.
To boot it , need to input 13 binary-machine instructions(like today's bios) in front pane by switch 16 switchers and store it into magnetic-core memory.then let computer execute it and read an OS paper tape into memory, then read compiler paper tape etc.
It is a mutiple- user real-time OS.


that is long time ago.
