I remember when I was young, you could put a transfer on a T-shirt by
printing from the computer onto Ordinary, bog standard paper. Then,
you'd mix 2 things together, paint it onto the paper and iron onto the
T-shirt. I can't for the life of me remember what the two things
I do know they were common household things, but my mind is blank.
Any one know?
When I was about 11 or 12 (1955 or so) my Dad, who was in graduate school at
the time, brought home an analog computer to do computations for his thesis.
About as big as footlocker, it was the first one I ever saw, and the first
time I ever heard the word applied to a machine.
I was familiar with the word because prior to that my Dad had been a
"computer" (one of the math whizzes who slipped a slide rule all day) on a
seismograph crew when I was younger.
I remember being real interested in seeing who this "analog" guy was that
Dad was bringing home.

I still have my log, log, deci-trig complete with leather case.
Still know how to use.
Although it's been years, most likely I could also. I used one exclusively
all through HS/college, and then again in the Army.
Just about any decent FDC (Fire Direction Center) guy (mostly math majors
and engineers during the draft years of the 60's)) could easily beat the
"FADAC" (Field Artillery Digital Automatic Computer), aka "Freddie", hands
down with a slide rule.
It wasn't even close.

Speak for yourself. ;-) I use an electronic E6B when I need something
for FAA tests. In real life, I use an Excel spreadsheet for flight
planning that calculates fuel burn and ground speed; I provide this
spreadsheet to my students as well.
I hate the mechanical E6B.

Our GPS has electronic E6B functions available, but I still use the

enough to list the formulas right on it, so it's a tad more intuitive
to use. I think it's kind of fun nailing down actual winds aloft
You could always use the metal parts to hunt game during an
unscheduled remote layover, ala "Survivorman". You can't use a
calculator to chop up a squirrel! <G>
My first introduction was when my father started working for Coastal States
gas Producing Co. in 1962. I was 7 or 8 when he took me down to the
computer room with the floors that had removable tiles for cables. The
computers filled the large A/C room and had those big spinning wheels like
reel to reels. It was not too many years after that in the 60's that he
showed me their rather crude but fast ink jet style printer.
When I was young I remember UHF being new. Some rich people had color
a few years later. My Dad got one of those high tech calculators. A
TI50 maybe. Heck it has been so long ago. One of those calculators
with the red numbers he used for work as an engineer.
I bought one of those 4 function TI calculators with the tiny red numbers in
1972. That calculator helped me fly through Physics in college. I recall
the calculator costing me 30% more than my tuition that semester.
I'm from the same era, and calculators were actually banned at NJIT (then
known as NCE - Newark College of Engineering) because only the wealthier
students could afford them, giving them an unfair advantage. Most classrooms
were equipped with giant working models of slide rules, 6-8 feet long and
mounted on a wheeled wooden frame, to demonstrate basic through complex
calculations in math, physics, and chemistry.
Fall of 1973 I sent a month's salary on an HP pocket calculator - one of
the earliest of HP's business lines. That thing lasted for 8 years or so,
until graduate school. It may still be hanging around in a box somewhere
in the attic. The one I bought in grad school, or it's replacement, is on
the desk next to my computer now. It's still the fastest way to do first
cut calculations on time and money flows. And they don't wear out, really.
Oh, I don't know... I've got a TI-92 (much newer, though a little
rare) that has survived for many years. I got one of the prototypes
in exchange for developing some educational software for it for one of
my math professors, and it has recently been granted a new lease on
life by becoming my wife's college calculator.
It's fancy, to be sure- the only calculator I've ever seen with
drop-down menus, 3D graphing, CAD (a light version of it, anyhow), the
ability to solve complex calculus equations and a full QWERTY
keyboard. But it's built like a truck, and has a hard cover that
clips over it. Could be it's not an import, but I don't see that
sucker ever getting wrecked by anything short of a house fire or a
I guess my reply was a bit vague. I didn't mean to imply that the
newer TI models, import or otherwise, wouldn't last as long as the old
basic TI calculator. I was speaking primarily of the Casio/RS/etc.
import brands which became mainstream competitors.
Since computers were coming into vogue, I never bothered with buying
any more calculators, especially since portability for field work or
classes weren't a factor in my usage of a calculating device.
Sounds like an on-site engineers dream come true.
Both HP and TI seem to be able to make assorted plastic parts fit
together with more durability and longevity than competitors - albeit
for a price. ;-) Probably due to the intended market audience.
(Which I am not a part of...)
My last calculator purchase (TI-89 Titanium) was a computer... At least
by definition. I'm very careful about mentioning that fact to my
teachers, as I sometimes smell fear of powerful calculators.
I'd have to say the school calculator environment (TI's market) is one of
the most hostile that you'll ever have a device in. You've got lots of
kids who have nothing better to do there than mess with and abuse things.
Most TI calculators survive, but not all do.
Wise is the man who attempts to answer his question before asking it.

Ah yes. The Casios are kind of junky when you put them next to a TI.
Same deal as the tool industry, I'd guess- they're almost 1/2 the
price in a lot of cases, so they get sold. I'd wager TI owes a lot to
the school system- most of which is still suggesting their products,
and using them almost exclusively. My wife bought a cheap one, and
then took mine after she realized that all of the buttons had
different labels than the teacher's.
I've always had a strong attraction/repulsion to calculators. I like
the built-in programming capabilities many of them have, but actually
feel like using a calculator for simple math is too much of a crutch.
Mine usually do duty as handheld units for collecting and interpreting
SPC data, or less useful things like playing old side scrolling video
games I putz around with programming from time to time.
Oh yeah- or even just a regular geek's. After the wife gets done with
her math class, it's going back to work with me. I don't actually
*need* it, it's just a useful toy for tracking SPC data that I'm not
actually required to worry about. (The boss doesn't seem to think
it's necessary, I just do it because I can.)
Most likely due to the target market, sure. The things have to hold
up to teenagers dropping them in a bag with a half-dozen huge, heavy
books with hard covers. If they couldn't take a beating, they'd be
useless to a lot of kids.
Never saw the HPs, but like you, I'm not part of the target market
anymore. Even if I head back to school one of these days, I can't
imagine *outgrowing* the one I've got, even if I majored in advanced
math or theoretical physics, which is pretty unlikely at my age. (I'm
not really "old" by most anyone's standards, but it's been long enough
that I imagine it'd be about as pleasant as a visit to the dentist
trying to get my semi-rusty brain to work that way again.)
