I re-created the Bendix G-15 Intercom 2000 from a manual. Not running,
of course, on a real G-15. Is there a

The IBM 1401 Fortran compiler 1401-FO-050 (subset of Fortran II)
generated machine code for integer operations, and bytecode for

One of my colleagues, about fifty years ago, wanted to use the 1620 for

Pascal was developed by one of Niklaus Wirth's students.

The "newer" version of Fortran is Fortran 2018. The working draft for
the next standard is https://j3-fortran.org/doc/year/21/21-007.pdf.

Not about early EARLY programming, but I have some books (manuals) that
are yours if you send me a PDF of a shipping label for a 10"x12" 1lb
2oz
I have some old stuff, that's not really computer stuff, so this might
be the wrong forum to ask.
But it might be the right people.

This is probably the wrong list to ask, but maybe somebody could
forward it to a more appropriate list.
I have several of my father's books on electrical engineering. If
anybody wants any of them, let me know.
