Hi
 It would have been trivial for them to adopt a simple
block transfer for serial binary at the begining. I suspect
that the reason they didn't do this was that they didn't
wan't people to transfer programs from machine to machine.
Can you imaging. 1 million people with computers and they
only sold one OS.
