Are you old enough to do these things?

I was working in a place where we weren't allowed smart toys, just big dumb terminals.

But I do recall when I was a freshman in college in 72 when the more flush engineering students stopped wearing slide rules on their belts and started wearing calculators.

'flush students', understandable...a cheap 4-function calculator with 4-key memory was $100...almost 3.5 days pay of the US mean income in 1972 !

When I graduated from college back then, slide rules were still de rigueur for science and engineering students, and calculators were not permitted

I'm looking over at the slide rule at the side of my desk right now, although I haven't actually used it since 1980.

I've a couple plus a small circular one I used in the field (surveying) before HP invented those awesome HP calculators.

In Oz it's called sly drool (See "Let Stalk Strine" by Afferbeck Lauder)

Who remembers Dan Dare on Radio Luxembourg, 205 metres short wave?

Best listened to after dark when the ionosphere bounced the signal back much better!

My old school slide-rule. I dug it out but realize I can't remember how to do much with it other than multiply. I'm sure there are instructions on-line if I cared to go that route. I left all the grubiness in the photo for old time's sake.

Captain Kangaroo was my favorite as a child.

I was on Captain Kangaroo

And what did you do "on Captain Kangaroo"?

This is interesting. Made by Aristo, a German company. I don't know what the HP stands for.

For those who took math and science classes before calculators made the scene, remember the large scale slide rules hanging in the classroom? They must have been at least 6 feet long. They were used to teach slide rule operations to students.

I'd like to know too.

Since typing that I have been desperately searching "youtube" for the video.. so far no luck. It was a short film about living in a sea town made filmed in Newport by local Newport RI composer that wrote TV jingels and such, and he made a number of these film shorts for Captain Kangaroo.

I'm so old and demented I've forgotten his name too,.

For sure, my first two cars had them

We lived in a very rural area with a lot of really bad roads so the tires were always making noise and we saved money by buying retreads

Yep, we had those windows. Just slide the lock and push them out.

...and a lot of the times I would ride in the front seat standing up when I was little.

We had an old dump truck that had a manual choke we would have to pull to start. Sometimes it would take a little starter fluid as well

Yep, and depending on what channel you were watching you had to turn them or spread them out more or less

I do remember that as well

We had three on a good day

We had party lines when I was young. Depending on the ring sound (two short rings) you knew who it was for. You had to listen for people picking up the phone to make sure no one was listening and tell them to please hang up.

Yep, as well as dialing numbers consisted of only knowing the last 4 digits in our area

...and putting your finger against the turntable to slow the record down for just the fun of it


Also.... My uncle had no running water in the house so we would have to manually pump water from the well if we needed water in the house. Also had to use the Out House. Not fun in the winter.

Today is the 25th anniversary of the 6.7 Northridge earthquake. Some may not remember it, but I sure do. My house was at the epicenter, and the shaking was so strong I thought the roof would cave in.
And it was loud, too. Not only from the rumble of the ground, but also from items crashing to the floor and furniture falling over. A very scary experience.
Anyone else remember?

I hear you, I was in the 1971 6.5 San Fernando earthquake when I was little and I remember having difficulty walking (trying to run). I remember the cabinets and dishes were making a racket along with the loud rumbling. Really scary.

My guess is it's for converting kW (kilowatts) to HP (horsepower) and the other way around.
A kilowatt is ~1.34 HP.
The center line (with kW) on the moving thingy is on 5.5 on the 4th scale from the top (B?) and the HP line is on ~7.37, which would be right.
Above that (A?), ~9.88 converts to ~13.24
Maybe.

HP is horse-power. It's a straight kWatts to HP conversion (1.34102).

Sorry, I didn't see your response. Yes, that's correct.
