Dan, see my latest reponse to Drew. I'm very much a novice at

on paper tape based operating systems, about 40 years before Linux).

Paper tape is better than manually entering the os by hand on a set of
toggle switches and buttons------------
Are you thinking in terms of the PDP-8?
I was part of the team that rebuilt the Manchester Baby (predecessor
or the Mark I) for the 50th anniversary of stored program computers.
For that you have to key in the whole program, not even paper tape
after you've keyed in the bootstrap.
I have to admit, we cheated slightly and interfaced it to a PC
which forces a store image into the memory on request, thereby
avoiding the long error-prone hassle. Tom Kilburn, the designer
of the original Baby was most envious when he saw it.

Oh man you really do go back!!! In school we had access to a working
PDP-8 and used , I can't remember the name of the system but it was an
1100 whatever mfg micro system that stored the code on 8" floppy to boot
the PDP-8. I seem to remember we had written code to make the micro
system look like a paper tape reader or card reader. I think the 1100
was based on the 4040 chip(s).
