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

Today i cleaned up and i saw a #olympia cd 80 #calculator from 1973. It wasn't in a working condition in cause of leaked batteries. I hate this, and i try to clean up the mess. Everything was clean, but the calculator didn't want to work with rechargable batteries. Than i test it with normal batteries, because they have 1.5v instead of 1.2v. With the first set of batteries it didn't work, again. I made more cleanings and used contact spray, toke another set of better batteries ..
And .. WORKING!

I 3D printed a support for a 9V battery that fits into the original battery compartment of the #TI57 and holds it in place. Here is the link of where I found it: https://www.printables.com/model/328550-texas-instruments-ti-57-programmable-calculator-9v/files Now the #calculator can be used again as it was intended

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!?

"In today's video, we'll take a look at my grandfather's vintage HP-45 #calculator from 1973"—so he opens.
As an #EE who used #HP #RPN calculators for my whole career, that word, "grandfather", hit me hard.
