(I can remember the simpler functions (multiply, divide & the
like) but how to use the thing for calculus &
whatnot I'm sure has
"slipped" my mind... (lame) Pun intended ;^>
Lame is right --
you're slipping.
You can'y use 'am for calculus...you must be thinking of trig.
And tho we did have some TRS-80 Model 4's (and an old IBM Series/1) in
high
school, I did use it occasionally during geometry /
algebra class when
necessary -- took it to college a few times to, but just to watch people
gawk... ;-)
I went through Navy Nuclear Power School in '76, and they were
required...even tho' calculators were cheap, then.
Texas Instruments was naming some of their calculators "SR" (for Slide
Rule) up until the mid-80's, at least. My first one was the SR-10...the LED
"wedge". $110, IIRC
Was that TI's first?

So my father thought, at least, when he bought the first one he saw, for
$140. My mother was appalled.
(He also bought TI's first, maybe the first-in-the-US, LED digital clock,
the TI-71. I don't remember how much that was, and suspect he never let
on, but it's here now, still keeping fine time.)
