The sandpaper pointing pads go waaay back. Prior to lead holders and Pentel mechanical pencils, there were specialized pencil sharpeners for drafting rooms. They tapered the wood part of the pencil, but left the inner graphite unsharpened--the draftsman then used the pointing pad to sharpen the graphite as needed. We also used them for putting a chisel point on pencils so that when lettering on a drawing, the downstrokes were thin and the horizontal strokes were broad.I am a nerd, and darned proud of it!
I had one of these bad boys for longer than I care to admit... Had it continued to function, I'd still have it, today.
TI-59c... with.... a card reader! Snazzy!

And what kind of cave man uses a sandpaper paddle?
Real nerds carried one of these... I finally stopped using 2mm lead holders, so I no longer carry it now.

And to this day, I carry 2 pens, Pentels in 0.7mm, 0.5mm & 0.3mm, 12 in metal ruler/scale, et al. in my 20+ yr old aluminum notebook... because it's better to have your drafting basics and not need them, than to need them and not have them!

Y'all have a great day!
Bask in all that makes you a nerd!
I still have a lead holder and one of those sharpeners. I never owned one but serious drafters had the metal sharpener that sat on the desk with a rotating part on top- put the pencil in a hole in the top of the sharpener and spin it around almost like dialing an old rotary phone.And, a WELL-EQUIPPED nerd carried one of these for on-the-go sharpening needs.
I have no idea why I still have this stuff laying around.

Was that the one that had a tiny Basic in it? I think Radio Shack rebadged it... I remember selling those around 1981 in my very brief career with them before I got a real job.Found these two in the workshop when cleaning up today:

The PC1350 was purchased in 1985 when I started my engineering degree. I only retired it earlier this year. It was always on my desk at work, and always getting used. Nowadays I use a scientific calculator on my phone, and have one less item on my desk.
Is it sufficiently geeky to say I also have the machine-language programming manual for that?![]()
Yep, the sharpener you are referring to was much more common, and was usually mounted to the table top with a clamp.I still have a lead holder and one of those sharpeners.

I've never seen anyone using a Pentel for professional drafting but I'm just experienced in a couple of different engineering offices. At my second company drawings were done with ink on mylar for the linework and the lettering was done with leadholders and "plastic lead". We had the electric erasers and I did own one of those at one time.
I've been involved with AutoCAD for most of my professional career and still do some work in AutoCAD including rocket drawings.
In my first drafting class one of the other supplies I bought was a "drafting set" which included a couple of different sizes of compass and one or two dividers. My first wife was in architecture and she kept that set since I didn't think I would ever need it again. However now I wish I had a small compass to use for creating custom centering rings and for laying out tapered transitions. I'll have to buy one on ebay.
There was a smaller single-line version that came out in 1980 I think, maybe a shade earlier. It was smaller than the PC1500 in the picture. I had that for a while before I upgraded too. That's what my memory is saying anyway.Was that the one that had a tiny Basic in it? I think Radio Shack rebadged it...

That's a nice emulator! I'm using RealCalc on my phone; I have my HP-15c for my computer and also Xcalc, both very old.
Of course they are! Why wouldn't they be? Once you've acclimated to RPN there is no going back. Ever. (Seriously, I've known a few HP users who had to use TIs for a while and went right back when they had the chance; I've never known anyone who used an HP for a while and wanted to go back to TI.)And even my computer & phone calculators are RPN.![]()
Yep, that's the one on my personal desktop (which is pretty much dead), and my personal phone, and my work phone, and formerly on my dead tablet. On my work laptop I have the upgraded version, Plus42, which I will also place on my new tablet (it's on the way) and my new desktop (whenever I get one). Second best calculator I've ever used, and the best was a PalmOS app that's defunct. (I never migrated to the 48 series; I have an emulator on my phone, and maybe I'll learn it one of these years.)
Dirty deeds. Thunder sheep.

I have a similar one for field work that I call my nerd box.
We used these for field work. It gave you a little edge over inclement weather. I suppose they were eventually "updated" to something made of plastic.

I've used RPN from the beginning- the first calculator I owned was an HP35. I have a couple setting on my home desk for work from home, one in my desk at the office for the occasions when I'm there, and a couple of spares in drawers somewhere. I've used Excalibur on my computers for a long time. It doesn't look like an hp but it is RPN.Of course they are! Why wouldn't they be? Once you've acclimated to RPN there is no going back. Ever.
That RPN saved my hide on many a Thermodynamics exam back when you did such stuff with paper and pencil and interpolating from tables. (Do they still do that, or is it all electronic lookup?) But man, you can interpolate in RPN considerably faster than conventional calculators, in my experience.I've used RPN from the beginning- the first calculator I owned was an HP35.

I almost never need to do calculations with my phone. One time I was on a trip and needed to do some calculations so after that I did install an RPN calculator on my phone, but also I make it a point to put a real calculator in my laptop bag when I travel.
I do own some simple type calculators. I have one simple solar one in my toolbox in the garage in case I need to do some calculations out there.
Do I qualify as a nerd?
Really wanted to make the ammonium dichromate+magnesium volcano(!!!) described in the book but couldn't get the chemicals...
Our junior high library had a paper back book, obviously aimed at juniors with illustrations and all, on making fireworks. Included all the recipes for propellants and explosives, with the various chemicals needed to get different colors and sparkly effects. I mean, there was some seriously dangerous stuff in there. Even back then (50 years ago), I couldn't believe they had this in the library. Probably for the better, I couldn't find sources for the chemicals.Do I qualify as a nerd? From years gone by:
Read older brother's 6th grade science book when I was in grade school. It led to annoyed parents because I'd make "flashlights" from batteries---taken out of working flashlights---plus wire and another bulb. Burned out a few bulbs as I learned about the difference between current and voltage. Later on I made some of the electric motors described in the book. (So very different from today's "science" books!)
During junior high I made alcohol lamps, a simple scale, flasks from old light bulbs, an electrolysis apparatus, a carbon-arc "furnace" (I'm surprised I survived childhood!) and other sciencey stuff from "700 Science Experiments for Everyone". Great book! Really wanted to make the ammonium dichromate+magnesium volcano(!!!) described in the book but couldn't get the chemicals...undoubtedly a good thing. They took that experiment and the carbon-arc-furnace out of the newer edition that I now have. Also probably a good thing.
In 6th grade we voted on the general topic for a term paper. I don't recall what topic was actually selected but I was the only one who nominated and voted for "Model Rocketry". Oh well, at least I got to write about it a few decades later...![]()
Depends on the era... TNG Command is red, Science is (still) blue, and Engineering is yellow.
