The Wang 450 desktop calculator is one of the last large calculators made by Wang. The 400 family was the last series of calculators made by Wang and the 450 Scientific is one of the series. This machine is no longer in my possession, it fell victim to my lack of storage space! I was also wary because the calculator had its original power supply and I was not confident the large electrolytic capacitors were still good after almost 50 years, so reluctantly I had to part with it.

But it is a beautiful machine! See for yourself.

This machine was made in 1973 and was probably obsolete as soon as it was made, handheld devices were by that time common (and much cheaper) and the first programmable handheld including a card reader (HP-65) appeared on the market only 1 year later.
