Sanyo CZ-8008
Brief History
There are some interesting models in Sanyo's calculator product line in the 1970s: the CZ-8008 used MOSTEK chip which can calculate only sine, cosine and tangent but can't produce its inverse functions! These trigonometric functions can be used with the F prefix button. The unusual model has only 8 digit capacity and lacks the exponential notation and has no memory.
