Cool.
"Since 2016, Maletic has amassed about 250 vintage calculators of all shapes and sizes. He’s putting about 100 pieces from his collection on display for a pop-up exhibit, “Calculators 1968-1983,” opening Aug. 18-20 in Portland."

Today I bought a used shelf with glass doors. And just finished moving the entire calculator collection. Much more spacious than before and dusting will not be necessary as often in the future.

Calculators now emulated on the Internet Archive.
"The Calculator Drawer is smaller than these other collections, but they possess a hearty collection of graphing and simple Calculators, emulated in MAME and with an additional layer of presenting the calculator itself, as a clickable graphical object, which you can then do math and graphing on."

A heady mix of #retrocomputing, #1970s #retrocalculators & #photography for Wednesday. Here's my HP-45: still in perfect working order, having previously been owned by a nuclear/aviation professor. (If you want to try one out, I wrote a terminal-based simulator which runs the original HP-45 ROM code for Z80 CP/M, Mac, Windows & Linux: HP45TERM is on my website.)

Snapped at the technical museum in Prague during the summer.

As you know, I also like older calculators. I got this little #Commodore #SR4190 years ago as an addition to a #Sinclair #ZX81. I'm still amazed that the two got along so well in the package. With a new battery pack for a wireless phone it runs nearly like the first day.

Turns out that Mastodon not only has a #retrocomputing community, but also a #retrocalculators community. So here's "The Usborne Pocket Calculator Book" (1982), explaining RPN.

#Olympia calculator #RAE4/30 with 15 digit Nixie tubes. Not really calcs something in the moment, but our radio mate works on it.

Interesting artefact.
"The Sinclair Instrument Wrist Calculator was a simple 8-digit calculator, that was only sold as a mail-order kit. It was released in February 1977 by Sinclair Instrument, a company ran in parallel with Sinclair Radionics. It originally sold for £9.95 (plus VAT)."

A twitter thread looking at the Omron 88 calculator.
"foone @Foone
Check out this fun calculator I found at a thrift shop this weekend:
An Omron 88! This is an 8-digit VFD calculator from 1975."
