As a card-carrying geek, I love me my techie toys. Fun tasks are made that much funner if they can be performed with a bit of technological hardware that adds an unnecessary element of convolution to an otherwise simple process. Unfun tasks can be made at least tolerable the same way. It's part of how my brain works. Same for a lot of geeks.
Take number-crunching as an example. As an engineer, I use numbers in some way on a daily basis. I've become fairly adept at performing simple arithmetic in my head. Say, for example, that today's gas price is currently sitting at 109.9 cents per litre, and I can tell you pretty quickly that, at 3.8 litres to the gallon, and about 95 cents to the US dollar, I'm looking at paying USD$4 per gallon for that trip out of town this weekend.
For anything much more complicated than that, I'm going to need my calculator. (Which tells me that number should have been $3.97 per gallon. Close.) But not just any calculator will do. No. It must be a geeky calculator. Yes. Many geeks will admit that the enjoyment of complicating a simple task through technology is further enhanced when that technology is, itself, unnecessarily complex. This may seem somewhat counter-intuitive, and you're right, it is. But no less true for that. My own experience can attest to the veracity of that claim.
The simple gas price calculation I made up there? I did it with my Hewlett Packard 48GX RPN calculator. I've had it since my first year in university, which pegs it at 14 years old now. Would you believe me when I claim that I get a greater glow of physical pleasure from using it than I do from a lame old ordinary calculator? I do. The buttons on my hp all have a subtle clicking sound to let you know, audibly and tactilely, that they have been fully depressed. It plots graphs, can perform calculations with complex numbers, has awesome statistical and financial library data, and just about every button has two functions in addition to the main function printed on it. I can store reams of text in its memory, play video games, transfer data to other 48GXs via infrared sensors (I call it "having hp sex"); hell, it even has its own programming language that I've never used.
So the fact that I rarely do anything more with it than perform arithmetic calculations and unit conversions (like from metres to inches, say), should stand as a testament to the joy I gain from utilising such a surfeit of technological prowess for something so mundane as multiplication. Like using a sledgehammer to crack a walnut. Overkill, sure, but WAY more fun!
But the best part? The very best part? Is what the "RPN" stands for in the title. Reverse Polish Notation. When I first heard the term I thought it was a joke, but it really isn't. It's an entirely different way to enter and manipulate data, that at first doesn't come naturally, but is totally intuitive and after some practice turns one inevitably into a calculator snob.
For that gas price conversion, most folks would use a normal calculator and enter:
109.9 x 3.8 x 0.95 =
to come up with the answer of 396.739 cents, or $3.97.
But using RPN on an hp calculator, I do that same calculation:
109.9 [enter]
3.8 x
.95 x
There is no "=" button on an RPN calculator. Techie, geeky craziness!
(Don't even get me started on the awesomeness of the slide rule I have in my credenza at work.)
The one down side of my lovely 48GX is its rather unwieldy size. I can't just pack it in my pocket and whip it out for unexpected trigonometric emergencies. It would barely fit, might break if sat upon, and, in mixed company, might appear grossly inappropriate if my khakis were viewed from the wrong angle.
Enter the hp 42S.
It's a pocket calculator with all the basic functionality of its larger sibling, the same crazy Polish data entry (see that big ol' "ENTER" button?), yet stuffed into a compact case that can be discretely thrust into a shirt pocket.
The problem here is that these bad boys were discontinued in the early '90s and the only way to get your hands on one is through second hand sales. I've had a hankerin' for one for a while now, so I finally broke down and checked 'em out on eBay. There weren't a lot there, but some.
I put in a bid, crossed my fingers, and waited to see if I got that email telling me I'd won my auction. A week later I got that email. I had entered the winning bid on my item. I was to contact the seller to arrange payment and delivery for my hp 42S Users Manual. Excuse me?!
I ended up paying for, and two days ago receiving, a 272 page manual featuring, on its cover, the calculator I thought I had won. I spent about 30 bucks on it, plus shipping from Florida. Turns out the actual calculators typically go for over 200 bucks on eBay, so popular, and rare, are they. I stuffed the manual in my desk drawer, beside the even larger manual for my 48GX.
I'm not sure yet how I'll console myself, but it'll probably be more complicated than it needs to be.
Sometimes I am amazed that we found enough common ground to consider spending our entire lives together. It must be that opposites attract cliche` I keep hearing about. I am still crazy about you even after reading this. Sigh.

I'm laughing at you, Simon, and commiserating with your wife. Hey, you can't expect anything else : I spent about 2hours this weekend - and more, if you count 'tape' shopping - watching over the baby, during which time Frank *had to* make himself a wallet out of duct tape (ordering them off ThinkGeek was apparently too pricey). A more tangible geek badge I never saw.
Now you'll have to let us know if you splurge 200 bucks for the gizmo : Amy will be deserving yet more commiserating. ;)

Well put, my fellow geek. And though we've previously discussed the fact that I have no similar attachment to my office tools...I am completley with you in the significance of the geek arsenal. I'm crossing my fingers in hope that you find some way to find your manual's lost partner. However..I find it pretty funny how you and the manual ended up sharing a desk. Too busy fantasizing about your new slimline calculator to actually read the auction detials? I do understand.
Posted by: Moksha Gren | Thursday, 07 June 2007 at 09:48 AM
Aim, I'm crazy about you too. I'm geek enough for both of us.
Émy, odds are good that I'll end up getting it. I should get a pretty decent bonus from work next month, and I may just be able to convince myself that I'm worth it.
Moksha, I swear I clicked on the actual calculator auction on eBay, and not the manual. My only guess, in my own defence, is that the calculator auction ended and timed out at the exact instant I clicked my mouse button, and I was taken instead to the manual auction and placed a bid without confirming I'd selected the correct one. That's the excuse I'm going with anyway.

I can relate to the inbred need to have geeky technology at hand just for the sake of it. Case in point - up until a few months ago, my basement was a repository for every piece of old computer equipment I could get my hands on. Lindsay finally made me recycle the truly useless stuff, though I've managed to keep my hands on a 486SX stashed at my parents house, and Mac Classic II carefully setup on a tv tray. Both of which serve no purpose other than to titilate my nerdbone.

I've actually seen that exact thing happen before, Si. You'd think the timing and probability involved would make it an incredibly rare occurrence...but if my old eBay customers were to be believed...it happens all the time.

Hi, Simon. My google blogs alert on "HP-42S" articles just pointed me to your post.
Sorry to hear about your misunderstanding. It IS a very good manual, though.
I love my HP-42S. I've had it since 22 June 1991, when I swapped a HP-11C to my uncle for it. He ended up sending the HP-11C back to me too about a year ago, since he found a simpler four-function calculator met his needs just fine.
I also bought a HP-48G on ebay in August 2002 for about $50, but I guess I found some of the same drawbacks you have with it so it sits in my nightstand.
That same month, when I thought HP was out of the RPN scientific calculator business for good, I bought a HP 32sii for my kids. I think it cost about four times as much as the 48G, ironically. My middle daughter uses it as her primary calculator for school. Of course now HP is back in the business, although the physical layout does not look as attractive as the old ones did to me.
We bought a HP-12C in 1988, but it came up missing a couple of years ago.
I doubt if you've stumbled on it yet, but I find that Free42 is a great substitute when I don't have my "real" HP-42 handy. You can see there that there are versions available for several different platforms.
http://home.planet.nl/~demun000/thomas_projects/free42/
It is not as nice as pressing the "real" buttons, but other than that works very well.
It would let you put your new manual to good use, and be sure you really like how it works before spending any money for the real key feel. I have my most frequently used functions and a couple of my programs assigned to the row of six custom softkeys across the top.
I have tried the Windows version a little, but have set up the Palm OS version as the default calculator on my Sony Clie SJ22. I usually use the real one when I am close to my valise and the Palm one otherwise.
The "standard" skin seems to be the easiest to use on my PDA.
It even has the advantage over the real calculator that importing and exporting programs is relatively easy. I have downloaded and installed several programs to my Palm that I would likely never be bothered to key manually into the real calculator one keystroke at a time (with no practical means of backing them up there either).
I use the BCD (decimal) version on Windows, as the arithmetic is a little more faithful to the original, but I use the smaller/faster binary version on my PDA.

Oh Simon. You make me laugh and sigh at the same time. Good post!

I'm with you on the love for an old calculator. I still have my first scientific calculator, which is a Casio with a solar panel that still draws power from a light source. I bought it around 1982. When the calculator's single-fold "case," is open, there are buttons available on the unit's face, but also embedded into the inside of the back cover. I almost freaked out when a schoolmate folded the back cover under the calculator -- I figured the wires were history for sure.
The main drawback to old trusty is that it had no battery backup at all. If you didn't have a light source strong enough to power it, then you just sat there staring at a blank LCD.
I've never owned nor even used a graphing calculator of any ilk. Somehow, I managed to finagle my way through high school and college without a teacher that required them. And, no, I didn't just take General Math.

Jayson, without sounding improper, I have to assert that the frequent titillation of one's nerd bone is a vital occurrence.
Moksha, I feel justified in my modicum of indignity then.
Bill, if you come back here to read this, thanks very much for your comment. Now I want my 42S even more.
Tal, I do what I can. I'm often just thankful that it's not so much that my wife can't tolerate me any more.
Mark, I hold the very strong opinion that calculators are, generally, one of the worst things to use in mathematics classes. To teach math, one should never have to resort to a calculator. It's a great aid in calculation, but it's become a crutch for far too many who just want the answer without knowing how they got there.

Only you could get me that interested in a calculator.

Abso-stinking-lutely, Simon! People can learn Chisenbop or even the Trachtenberg system if they have to do basic stuff.
Now I have "Pocket Calculator" by Kraftwerk in my head:

I hope you'll find and acquire your vintage calculator soon, Si.
But will it fit in your pocket protector, next to your fountain pen?
