Well .. impressive, I suppose, would be what I would call it.

I guess you'd start with hand-keying in an assembler .. then go from
there.    I did that once in BASIC on a machine for which I could not
obtain an assembler (Epson HX-20).

It would be interesting to know how they went from B to C .. but once
they had a higher level language (C .. well, higher level compared to
the assembler), things would become much easier.

I was corresponding with DMR a couple of years before his passing.  He
signed his C book for me.  If he were still around it would be cool to
loop him in on this stuff and just ask.
