Novus 850 Calculator

I don't know if this belongs in here, but i just found a old Novus 850 in my grandpa's shop, still had the original battery in it, (needless to say, that didn't work,) but i cleaned it up and put a new 9v in it, and it works flawlessly.

Upon some research, i found this was made in 1975, has an LED display, and uses LSI technology (anyone know what that means?) and its the rarer black version instead of the more popular cream colored one.

Does anyone know if this calculator was anything special?
