I started with computers around 1964. It depends what you define as a 
 From the first UK computer (U of M circa 1948) many systems had screens.
They were oscilloscope tube based. The first one's I know of showed a 
line of dots
Dot present = 1 No dot =0 they were probably register displays.

So right away you are into binary. Its the underlying foundation of all 
digital computers.
Lamps and switches are all you need for binary and boy is binary useful!!

Analog computers are interesting but you really need degree level maths 
to get the best out of them.
