Ah, but the normal process would be to enter the boot loader by hand,
then a bigger/better loader from paper tape and then the actual OS.

Or did you actually write naked assembler code to do things direct
with the hardware?

I started at a similar time (early 1970s) on a wierd device called the
PDP-12 (an odd marriage of a PDP-8 and a university developed machine
called a Linc-12).
