That thing is way older then me. Cool to see tech from back then. Glad to have you back!
I inherited one of these calculators when a grandmother died. No box and slightly roughed up, but it still works!
Nice retro movie camera, BTW.
Looking forward to more retro tech. That stuff brings back the memories. I remember buying my first calculator back in 1977 for use in college. We couldn't use it in class, still had to use slide rules for physics and statistics, but they got a lot of use at home for homework.
Love retro tech. Liked the way you worked in a Hitchhiker's Guide to the Galaxy quote.
I’m loving the new retro tech segment
Good to see you are back!!
I love the way the keys clicked on those old Texas instrument calculators. All calculator keys nowadays just sort of mush.
It is great to see you again Chief. Hope you are feeling better brother.............J
Glad you're back Fred. Thanks for the video
Keep up these vids I'm glad to see you back on CZcams
Great new series
Good to see you back again. Love the retro series as well as your past work. Not sure why I did not before, but I did subscribe now. Looking forward to seeing more reviews
This calculator was the basis of the Engineer's PDA from TF2
Nice video, incredible how fast technology went.
Man this bring back memories!
Good to see you!
I enjoyed this video.
Retro tech is a cool idea!
thats a really nice peace of vintage office electronica. pretty good shape! 8 bucks? boooom... amazing!
i love those old fashioned red digits.
thx for sharing buddy!
greetings from cologne, germany

Fred is back! I am so glad to see your return..
Welcome back Fred. Missed you man. I like the retro angle.
FRED!!! You're reviewing stuff you're genuinely interested in and having fun doing it. We can tell. Makes that vid that much better. Welcome back!
He didn’t seem that interested in it.
Too cool. Wish I had kept my aunt's old slide rule pencil case.
Miss you my great friend!!!
@@GearObsession likewise. So happy you are in good spirits and doing what you love again.
I remember my parents having a Sharp Calculator from late 1970s or early 1980s. Had a green LED display and used 4 AA batteries.
ThT Pentax is nice. The parents still have a working Canon AE-1
I did enjoyed this video, I think the retro videos would be great 👍🏻
Welcome back .
Great vid Fred!!! Do more videos on vintage items maybe! If you can find them lol
My first hand held calculator would only x+-and /. I got it on my Gulf CC and it cost me $100. Much later in the late 70s, I had one of the TI's like yours. Can't remember what it cost me then.
Holy cow that's oldschool :D
You'd could get a decent price on Ebay for that with the complete box and adaptor and paperwork.When I was in tech school, many decades ago, the TI SR-10 was what I had. Your inner nerd was in full flight if you had one of those hanging from your belt! It was at least $100. Of course the guys with Rich Dads had HP's!!!
the battery on the meter can easily exceed the cost of the camera. i had an old bell & Howell. it was great fun.
Back when electronics were simple lol great vid!
Wow! Its refreshing to see an old linear power brick (I think that's what it's called)
I love the old stuff. Well I owned all that stuff! Guess I am old then also. :-) I had the Cannon AE-1 camera myself. And yes I had the red led watch.
K+E Decilon slide rule to the 'new' TI calculator in early '70's for mass real estate appraisal work for a large
county on the west coast [U.S.A.]...memories!
why Fred...I'm surprised that didn't have a choke and hand crank...LOL
Cool old stuff
I still have my Pentax ME-Super I bought in 1980. Going out for the day with 36 shots tops was a thing :)
I think I had an LED TI calculator that took a 9V battery. It lasted about an hour if you don't turn it off after making a calculation. At best, I think I could get a week out of it using it a few times a day...lol
So..Fred ..I am sure there is no link to Amazon on this one lol
Yep, I'm positive, none there :)
E-bay link maybe ;)
In 50 years someone will make a video like this for a ti-83 and they'll still be selling them for $100
Is this being sold again or something?
The ones with a lever on the side of em are a lot faster .
Fred!
Good evening :)
Hey Fred! How ya doin'?
I'm doing fine, thank you :)
1970s $50 = $320 2017 (per inflation online calculator)
This was a bit boring for me
