I have a Sharp microwave, bought in about 1983/4.
Still works well, but I have to keep an eye on the electro-mechanical timer, it has a happy knack of sticking from time to time.
On the subject of opening the door, it has a two stage push button,
press the button and it kills the power, press the button a bit further and it opens the door.
Pressing that button is the only way to open the door, there is no handle to pull the door open.
