   That should be EASY to do by using the ROM monitor. You shouldn't even
need OS software to do it. The monitor command R0 reads from the paper tape
port. I imagine that you could use another device to input data there
instead of the PT reader. You could then use the monitor commands to write
to a disk and you could concievably create your own OS disk that way. If
nothing else you can use the monitor to store anything as a block of data
on a disk and then retrieve and run it later using the monitor.
