Something small: The Internet Archive has added a new family of simulations to its ever-growing repository of ancient technology. The calculator tray is a new set of simple calculators and graphics simulated in MAME, a free and open source emulator first released in 1997. The calculator tray includes an additional clickable graphical layer enabled by the MAME Artwork System with which they can interact with them as if they were right in front of you.
Jason Scott of the Internet Archive goes further the details About how the technical MAME system works and how more than 1,400 systems have used it to date.

Depending on your age, a graphing calculator like one of the above examples from Texas Instruments may be a requirement for higher-level math classes in middle or high school. If memory serves me correctly, it worked mostly with the TI-82. I’ve never gone down the rabbit hole, but I remember other students working all sorts of neat tricks on their calculators and even figuring out how to upload Toys on them.
the a group Accompanied by a pile of Instruction manuals For those who need a refresher on how to get the most out of them.
For those who crave the real thing, Texas Instruments still markets some of the above calculators including TI-73 Explorer and the TI-84 Plus. Older models such as the TI-82 are readily available on third-party marketplaces such as eBay for a fraction of what they sold for when brand new.
