1976 Texas Instruments TI-30 Scientific Calculator

Hi everyone!
Today I'd like to share with you a new addition to my calculator collection: the TI-30, given to me by a friend who got it from a thrift shop. Quick Google-fu will show that it's not especially rare or valuable, but it's an important part of my collection because of its historical significance. It was one of, if not the first affordable scientific calculator - released at a time when most peoples' most powerful computing device was their handheld calculator, and when most calculators of similar functionality were above $100. This one was released for $24.95 and it sold in the millions.

Those circles around the numbers are lenses, to enlarge the small, power-efficient LEDs. This allowed for better battery life. (Blatantly copied from the HP-35.)

Assembled in USA.

New Project: Scribomechanica.com

Hi everyone,

I've started a new website, dedicated to writing instrument reviews, including pens, pencils, and fountain pens (with typewriters coming this Thanksgiving once I get back home)!

Created with my Brother Deluxe 220 and Pilot Metropolitan fountain pen (Noodler's Black ink)!

It's called Scribomechanica, located at scribomechanica.com. Do check it out and let me know what you think! I hope you enjoy it.

Thanks,
Vikram

On the subject of analog vs digital for everyday things

Thought I would write a little bit about when I use analog tools and when digital is needed.
