his got me to thinking.

For me  the year was  1962, the computer  was an IBM 709,  serial number
NASA-1,  at  Washington State  University.   My  first  and only  formal
programming class was a FORTRAN lab  that met at 0800 on Saturday.  This
was the  semester I turned  20 and could  legally drink beer  in Moscow,
Idaho, 8 miles from campus.  So I attended The first and last class, and
took the midterm.  All of  the program exercises ran correctly the first
time I submitted  them, although I did make several  mistakes at the key
punch.

I got a D -- something about attendance.

I  can remember sitting  in the  machine room,  lit my  the glow  of the
vacuum  tubes, at the  709 console  entering small  programs on  the M-Q
(multiplier-quotient) register keys and  then watching the lights on the
console blink.  I think the cycloids machine was about 1.8 milliseconds.
Quick, no?

I went  on to spend most of  the years following until  my retirement in
2004 in software, I think rather successfully.

It is good top remember the early days.  No os, booting the machine from
a bootstrap loader on a  single binary card to get the "FORMON" loaded
from tape at 800 BPI.

Oh, the other stories we old crotches could tell.
