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. > On Feb 26, 2016, at 5:24 PM, Johnny Billquist <[email protected]> wrote: > >> On 2016-02-26 23:47, Eric Smith wrote: >> I love assembly.
