The last really good thing TI ever did. How do I know? Because they're still selling a dumbed down version of this same machine. The TI-92 was really a general purpose computer with a computer algebra system as it's front end. With a 10mhz MC68000 and 64k of RAM it could be made to do all sorts of interesting things! #calculator #retrocomputing #ti

I was recently gifted of a magnificent #TI57 programmable #calculator. The LED display is amazing and I love it However, I would like to have a little chat with the engineer who thought it was a good idea to use a red wire for the negative and a black wire for the positive connections of the 9V battery. I’m glad I first checked online. I could have destroyed it on the first attempt. In the battery pack the NiCd elements are leaky and much probably the boost converted is gone, too.

According to the #macos #calculator when in "programmer" view, 2560/1080 = 2. wat!?

Gonna have some help learning how to slide-rule

Waiting for the 5 min epoxy to dry on my repair to my Frankenstein HP-41 #calculator. I like having a backup machine in case my daily driver breaks.

It’s got a spare parts keyboard but I had to replace the LCD screen after I toasted the original by resoldering the pins on the LCD itself, which I later learned is a no-no.

#Calculator on my desk this week. Ti-37 Galaxy Solar produced in 1985.

I found a kewl compact long-period clock for Minecraft redstone yesterday, but calculating the settings to get the period I wanted was a pain.

With a bit of HTML, CSS, and JS and an unknown amount of my evening, I am now +1 period calculator for said clock:

Context: I've been quite enjoying the puzzle aspect of Minecraft redstone when designing contraptions for a survival world I've been playing for the past ~1-ish years (I forget exact start date), and I wanted a cactus flower farm.

Cactus flower farms, according to the wiki, need a period of 34 minutes and 6 seconds.

Tell me about your favorite #calculator?
