In recent years I have managed to collect a certain collection of retro equipment. These are mainly calculators, but there are also a few other devices. Below I've posted an inventory of my freebies😄 if a particular model is underlined, then when you click on the name it will open a resource I've prepared about its construction, history and operation. Also, I've thrown in the names of a few pieces of equipment that I'm looking for, if you have them, get back to me at my email address rafal.barto2808@gmail.com.
