If you need a sliderule, there is one on my desk.......but I can't find a
slot in this laptop to interface it with otherwise I would send you a
copy...

Let me see there is a USB, PCMCIA, silicon card...........................

Hi, Werner and Inge
I remember that most of the old algorithm development was done on a
combination of advanced calculators (they had a root/square function!)
and sliderule calculations. I remember when I calculated Cartesian
coordinates using this method, and then I stored all of my insertion
machine programs on punched paper tape or IBM data entry cards. There
wasn't any such thing as Gerber data, everything was designed on film.
And I remember how the card or tape readers never quite worked right all
the time. I learned to stand back the first time I entered a new program
into the machines and pressed "go".
I believe more algorithmic "macros" were actually developed on the HP
22-series calculators than were ever developed on the first mainframe
computers. I do remember that the HP-35 could run programs that the
concurrent IBM mainframes were not capable of. Even when the first Apple
computers came out, the HP calculators were much more powerful at the
time.
Does this jog your memory: http://www.hpmuseum.org/35proto.jpg ? I
believe it was the first calculator that had all or most of the
sliderule functions. I wish I still had mine.

Hi Inge,
We were not totally without tools---we had sliderules; remember those.
