I always used 80085 instead of 60065.


skilas t1_iwvydmt wrote

I've never seen 60065 used for this before. I thought it was a typo...


intervested t1_iww0tcx wrote

Looks like it just works because of OPs particular calculator. Most would add the bar across the top of the 6 and it wouldn't look like a lower case b.

As I mentioned elsewhere in the thread. Will edit..


Aenyn t1_iwxn3dg wrote

Huh because of the shadow at the top I thought there was a bar on top of the "b"s. Didn't notice there wasn't until I read your comment

For some reason I assumed a bunch of Reddit calculator nerds would also know what hexadecimal is. Thanks for giving the explanation.


RegularSizeLebowski t1_iwz9p3v wrote

Not just space saving, but also convenient to read when dealing with bytes because a byte is exactly two characters.

So do I, it seems to make more sense like all upper case letters. That looks more like 6s to me than lower case bs with upper case other letters

Gotta give them credit for battling inflation, too. A new TI-89 cost $130 in 1999. A new TI-89 costs $130 today, too!


AeroZep t1_iwy1ytj wrote

The cost to make a TI-89 in 1999 was probably $100. The cost to make one now is probably $5-10. Let's not give them too much credit here. It's not like they have made any improvements to their product.

Luckily you can thrift them for <$5 pretty commonly. In fact, I have a $2 one sitting on the desk next to me right now. So many high school kids buy them new then leave them sitting around until their parents donate them it's silly. I've probably purchased at least two dozen over the years...for my kids, for their friends, and then quite a few I flipped on Ebay for $50-60.

True story: two football players who lived on my dorm floor were waiting for the elevator, on their way to a night math exam. One pulls a new calculator out to show his buddy: "It's solar. Now I don't have to worry about the battery going dead during a test."

His buddy puzzled on it for a minute then said "Yeah? But what if the lights go out?"


BeerNTacos t1_iwxkf0w wrote

As a calculator nerd, I know the exact model this is.

It's not the original TI-36 SOLAR but the 1989 revision, the second model.

The solar cells on that calculator are smaller than the original version, plus the "ANYLITE SOLAR" language wasn't used until the 1989 revision, and ONLY for that revision. The bottom text said "SCIENTIFIC" for every model before and after, The depending on the year's revision the text was either lower center or lower right.


lake_huron OP t1_iwywqal wrote

I had this in high school which was before 1989.


BeerNTacos t1_ixb0g5h wrote

Okay, I did a little digging around and contacting some old folks who knew people back in TI's earlier days.

The records back then are not great but it seems this model is definitely the second model, but there seems to have been some earlier models of this version made, possibly as early as 1986. Original version came out ~1985 but used the TI-35's solar cells. This version specifically used the ANYLITE SOLAR designation to differentiate between the two models. It wasn't until ~1989 that TI advertised this version. Even then, outside of this naming convention they were using the packed in 1985 materials come out like the original manual.

Back in the day I used to sport my HP 48GX, but by the love of god I just can’t figure why would anybody cling to older devices having a regular calculator on your phone or having access to wolfram alpha on it.

Sometimes the calculator is nice because it keeps you from losing hours down a wolfram alpha or Wikipedia hole! Good for focused work


TenTonneMackerel t1_iwzd83z wrote

Because 99.9% of my calculations at work don't require anything nearly as complex as Wolfram Alpha, and the ergonomics of a calculator are leagues beyond that of a software calculator on a phone or computer.

I check the bins hoping for an RPN HP every time I hit the thrift stores. No luck yet, and until I finally make that score my daily is still going to be pCalc on my phone, but in the meantime I’ve picked up quite a few nice clean ‘70s and early-‘80s models for a few bucks each.

My two Radio Shack-rebadged Casios from high school (early-Reagan-era) also still work just fine. I think I’ve replaced the batteries on them maybe twice since they were new.

Liambp t1_iwy4xhy wrote

I actually think the mid 1980s was when calculators peaked. You could get scientific calculators like the above that were packed with every function you actually needed (note the calculator above had stats, hex and even complex) but none of the bullshit that later became popular like direct arithmetic entry and calculators that give you answers as fractions. The thing is that computers were not ubiquitous yet so real life professionals like engineers and scientists actually used calculators every day and they had to be functional. Nowadays calculators only seem to be used by students.


lake_huron OP t1_iwywbjj wrote

Yeah, even small features helped.

There is an Engineering setting where all scientific notation was in exponents that were multiples of 3. Perfect in grad school when I wanted stuff only in nano, micro, milli, etc.

I agree. The calc app I use is pretty similar to this TI


Liambp t1_iwyywgu wrote

That is such a useful feature. I had a Casio calculator with a button called "Eng" which did something similar. It was incredibly useful for converting an answer to k. M, G etc.

I have to ask, because it was emphasized, why would calculating in hexadecimal be anything different for the calculator.


lake_huron OP t1_iwyw0t0 wrote

The "b00b5" displayed is in hexadecimal, so just calling attention to the juvenile joke.

Some commenters are saying 'wow that's a funny-looking 6' when it's not.


real_with_myself t1_iwz7glk wrote

Ah, yeah. A bit too old for those jokes.

But I remember, back in Serbia, we had a similar joke that would spell "fuck you"


SnowblindAlbino t1_iwz42pe wrote

Calculators in general were pretty damned well made in the 1970s/1980s because they were relatively expensive. Or actually expensive, in the 1970s at least. I "collect" (read pile in the closet) old calculators and about 90% of the ones I find work just fine after decades of sitting around. I prefer the LED models from the 70s (esp the blue ones) but have probably three dozen <1990 calculators and they all work great with fresh batteries. Including the programmable Sharp model I bought originally in 1983.

Not so sure many calcs purchased new today would still be working in 30+ years.
