Review: Clip Calculator with Magnet 2606

Novelty calculators are generally terrible, especially novelty calculators ordered on Ebay for about a dollar from China. I have yet to find myself happy with a single purchase of this type, but as a calculator collector and reviewer, I have to let the people know about them. The calculator reviewed today is no exception. It's terrible.

Clip Calculator with Magnet 2606.
The Clip Calculator with Magnet 2606 (I'm just going to call it the 2606 from now on) is a calculator, a magnet, and a clip, but is only decent at being one of those things.

The magnet is incredibly weak, probably only strong enough to support the device on a refrigerator. I suppose you could hang a sheet of paper or two with it, but you likely have other, much better magnets already.

The clip is strong. It'll hold a bag of chips shut. That's the one positive thing I have to say about this device.

Here's a picture of the calculator not working.
And finally, the calculator doesn't work. The battery is probably dead, but I only ever turned this device on once, shortly after it arrived in the mail. To get to the battery, I had to disassemble everything and that's when I found out I didn't have a battery that would fit in it. That was disappointing.

When the calculator did work, for my brief test upon receiving it, I felt nothing. I had in my hand a calculator that could keep a bag of chips closed. The buttons were too small to use comfortably, and the LCD screen was utterly unremarkable. It could do the things a simple calculator is supposed to do, and nothing more.

So that's my review of the 2606. Don't buy one.

Review: Canon P101-D

Like any vintage electronics collector, I love retrobrighting and restoration videos. They are a huge part of what got me into it in the first place. Seeing a device that would normally be thrown into the trash restored to its former glory is extremely satisfying, and a high that I've been chasing for a while. Here are a few of my favorites:

Extreme Refurb: Atari 800XL | Refurbish This! - Perifractic's Retro Recipes

Commodore 64 left outside for over a decade! Could it still work?? - Adrian Black

Commodore PET Repair and Restore - The 8-Bit Guy

These people are much better than I am at restorations and creating videos, but they have inspired me to be a part of this subculture that tries to keep old electronics working for people to appreciate. 
Canon P101-D.
That being said, I have utterly failed to retrobright or restore the Canon P101-D that I recently purchased at Goodwill for $10. When I first laid my eyes on it, I was thrilled to see a device with such a bold orange color. This was the kind of desktop calculator that would turn heads at any cubicle farm. I was going to make other calculator collectors salivate over my unique find. I needed this after learning that a fellow collector owns a Curta. 

Proof that I talked to a person.
This was followed up by an image of what the calculator is supposed to look like:

Source: not me.
Needless to say, I was devastated. But I also saw an opportunity to attempt my first retrobright. The video attached to this review shows my process, and I'm trying to get more views, so if you're interested in seeing how that went, check it out. To quickly summarize, it didn't work at all.

The Canon P101-D is a fantastic desktop calculator regardless. It's quite large but doesn't feel like it's wasting space. The numeral and operation buttons all press like mechanical keys with instantaneous responses. The exception is the "paper feed" button, but not at all in a bad way. It has its own sort of deliberate feel when pressed.

Very sturdy and reliable internal components.
When using the printer, every calculation is loud and mechanical, and it's awesome. It feels like a large cash register when this thing really gets going. It's hard to explain, but while loud and mechanical might seem annoying, it feels more like a reminder that this device will probably continue working forever. 

And of course all of this leads up to the absolutely gorgeous green LED display. Even with a cracked display cover (my fault), numbers have never looked better. This is simply a beautiful, solid calculator that I will proudly keep on display. 

I'm tempted to leave it in the sun for a bit to even out the discoloration, but there's a possibility I'll be revisiting this device in the future with another retrobrighting attempt. 

I have contacted Canon customer support to try to find the release year for this model, but they were unable to provide me with an answer. I've searched around for the answer and have found nothing so far. If you have any information about the release year, please let me know so that I can update this review.
Cracked screen (my fault). Still looks great though.

Review: Texas Instruments 108

I like to begin each calculator review with a brief paragraph about something other than calculators, then segue seamlessly into the review. It gives each review its own sort of personality and keeps things fresh.

If you've never seen or heard of the TI-108, it means you haven't been inside a school since 1986. These things are everywhere. You can buy them in packs of 10 for like $30 on Ebay. But just because something is common and used by everyone doesn't mean it's necessarily good.

Yet the 108 is one of the best calculators ever created. Sure, it lacks any unique features, and can only perform basic operations, but just look at it. Seriously, find the nearest kid and take their backpack and dig through it until you find one. You most likely won't find a scratch on it, and it's definitely going to work. Texas Instruments made an extremely durable calculator that even a child would struggle to ruin.

The buttons are colorful and coordinated, have a great tactile feel, and everything is right where it should be. Not that it's needed, but they included a solid cover for added protection. It's impossible to tell how old a given TI-108 is because these things don't age. The solar cell works perfectly every time, so there's no need for a battery.

I really tried to find something to dislike about this calculator, and maybe nostalgia plays a role, but the TI-108 is simply perfection. These have been widely available since 1986 and will probably be used in elementary schools for at least the next thousand years. I got mine on Ebay for $4.

Older and newer variations.

* * * UPDATE * * *
The above was the initial Facebook review, but I have since learned that the TI-108 has at least two variations, both of which are discussed in the video review. The older version runs on pure solar energy while the newer is dual-powered. They also have slightly different external colors. Internally, they look like completely different devices.

Regardless of the variation you get, you won't be disappointed with the TI-108.

Review: Unknown Curved Calculator

Hi fans of calculator reviews! It's been a while, I know. This has been an eventful past few weeks, but now I'm back to my boring life so the most interesting thing going on for me will be taking apart and reviewing calculators. Thanks for being patient with this free content.
Unknown Curved Calculator.
For the first time in my calculator collecting and research, I am unable to find the origins of a particular device. I don't know who made this calculator, and I don't know if I'll ever be able to figure it out. What I can do is hope that someone comes across this blog who might have some information. Until then, this device will be referred to as the Unknown Curved Calculator, or UCC.

I found the first UCC at Goodwill a while ago with some company's label on it. It looked like a decent enough calculator with its silver face plate, nicely contrasted black keys, and a relatively large, tilting LCD display. That tilting display is vital because if you intend to use this as a desk calculator, the curved design would otherwise prevent easy viewing. It is kind of strange that the designer created their own problem to solve, but the curve is quite nice.

The tilted screen solves the problem it creates.
While the buttons look great, they're quite unsatisfying to press. They work consistently, but there is practically zero tactile feedback. It's hard to explain, so if you happen to be in the area, we can meet up and I'll let you feel them. Just don't make it weird.

I did find and purchase two of these devices, and the first one was destroyed during the disassembly phase of this review. It's all well-documented in the provided video, but to summarize, the internal components are actually very nice, with the exception of the ribbon connecting the main board to the display. It's incredibly fragile, so it broke and I killed the calculator.
The first device had a battery access panel, but the second did not.
This creates a predicament for me as a reviewer. Yes, it is my fault that the calculator no longer functions. The device has an access panel for the battery, so most people wouldn't bother taking it completely apart. However, the second calculator I purchased, while nearly identical, has no such access panel. To change the battery, I would have to disassemble it in the same way I took apart the previous calculator. I have not taken this one apart because I'm worried I'll destroy it, so when the battery dies, I'm not sure how I will handle that.

These are promotional calculators, as indicated by the irrelevant labels on them. Most promotional calculators are designed with less consideration for the end user, and this device is no exception. It looks great, but you're way better off getting something more reliable. It's a shame because I don't typically see curved calculators. This device stands out aesthetically so I'd love to find a more quality device going for the same look.

I found both of these at Goodwill for about $2 each.

Still Here

Hello, and welcome to the calculator review, hosted on calaquin.com (except not right now).

I apologize for the lack of content over the past few weeks, and I apologize for next week too, because there likely won't be much content then either. I'm on my winter break from school so this has been a time for me to relax and be as lazy as possible.

Despite the lack of content, I have been working on some material for upcoming reviews. I'm excited about it and can't wait to show everyone. It's not quite ready, but it will be soon.

Next week I'll be going to a gaming convention, so it's not likely that I'll have much to share until the second week of January.

The three reviews a week schedule will resume some time next month. Until then, I hope everyone's okay with sporadic updates for this content that I pay for you to enjoy.

Also, calaquin.com is currently not working. I'm trying to fix this.

Review: Sharp EL-8141

Today is Christmas Eve, which means we're only fourteen days late for Hanukkah! But not to worry, because it's only 311 days until Halloween! To t̶a̶k̶e̶ ̶a̶d̶v̶a̶n̶t̶a̶g̶e̶ ̶o̶f̶ celebrate the holidays, I've got a special calculator to share with you and review.
Sharp EL-8141.
The Sharp EL-8141 is tiny. It's about the size of a credit card. Even in its leather case, it still fits comfortably in my wallet. Credit card-sized calculators are common these days, but the EL-8141 was released around 1979 and looks better than the devices people hand out for free.

It also feels better than any free promotional calculator. It feels like a solid block of metal that won't bend without a significant amount of effort. The buttons are flat and have no tactile feedback, but surprisingly satisfying to use. Digits display effortlessly on the LCD screen and the calculator has an optional beep to indicate a button has been pressed.

Back of calculator.
I purchased this calculator specifically because of the musical note button. I thought this was going to be a musical calculator similar to the Toysmith Rock On! Drumkit Calculator. Sadly, this is not the case. That button only turns on or mutes the beeping noises whenever buttons are pressed. Still, it provides some unique functionality you don't always see in a device, especially one this old and this small.

The one notable flaw with the device is its use of two LR1120 batteries. The entire back of the calculator must be removed via a single screw to access the battery compartment, so this probably isn't the best one to take into a situation that requires reliable mathematical operations.

With its sturdy leather case and sleek overall appearance, the EL-8141 is a must-have device for any calculator enthusiast. As previous reviews have suggested, Sharp tends to nail their designs and I've been happy with every device I've looked at so far.

This Sharp EL-8141 was found on Ebay for about $11.

Review: Casio fx-300ES PLUS

This Facebook review was modified for privacy reasons. It's also inaccurate because this was originally posted a while ago.

Yesterday my brother [REDACTED] and [REDACTED] got engaged, and I'm so happy for them. To celebrate this, I could think of no better calculator to review than the Casio fx-300ES PLUS.

Casio fx-300ES PLUS
Most of the calculators I own are at least twenty years old, but every now-and-then I come across something newer that is too good and inexpensive to pass up. The Casio fx-300ES PLUS is the third generation of a proud line of calculators often used for SATs and other nonsense academic testing. It's not quite a graphing calculator, but it's definitely not your average statistic or scientific calculator either.

Eight digits is, for some reason, the standard limit for most calculators. It's always interesting to see this limit be different, but what makes the fx-300ES PLUS- as well as its ancestors- so special is that there doesn't appear to be such limit. I typed dozens of numbers in and the screen just kept scrolling over to allow more. In fact you can type in massive equations and this modern masterpiece will handle them.

The scroll function is also a fantastic feature, allowing you to correct mistakes even after running an operation. This is on top of tons of other features that I simply don't feel like reviewing.

Released in 2012, this calculator is by no means vintage. It's made from a strong plastic and every button is clearly visible thanks to outstanding color contrast. It runs on a single LR44 battery and is aided by a small solar cell. I found it at Goodwill in a basket for $4.99.

If you'd like to learn about all of this calculator's features, Casio still has the guide posted on their website. Check it out here: https://support.casio.com/pdf/004/fx-300ES_PLUS_E.pdf
