I presume so - this is November 1928, so this must be a Baird system TV.

Where’s the screen? That little disc?

Yes. Early TVs used a spinning disc with little holes in it, which is what takes up the rest of the cabinet. This design preceded CRT TVs. A bank of lights behind the screen switch in sequence with the disc to produce apparent lines which in composite form a very low res monochrome picture. I built one for a school science project back in the day., drilling holes in an old LP. We used a large fresnel screen to magnify it.

Most of the flowers on that chair fabric look like screaming faces, and if I was part of that upholstery I think I'd join in.

Also, with formal wear your socks should match either your shoes or your suit! Gah.

Some times I almost think the past *wasn't* better.

Perhaps the viewer is colour color blind but was chosen so that he could say (truthfully, as far as he was concerned) that the black and white images were in colour color.

Hey, back in the 90s I started playing Doom on a 386sx. In order for it to run fast enough I had to shrink the screen to the minimum. It was about the size of a 3x5 card. LOL

First known use of the word "Internet" - as a model name for a 1954 transistor radio.

As Jan would point out, it looks as big as the real thing.
And It's clearly wasn't wireless in those days.

All these years, I've been thinking that Jan (and, more particularly, the writers of the IT Crowd) had got it all wrong....

A bit later than this, but I remember the days when transistor radios used be proudly emblazoned with the number of transistors in them.

Working on computers in the space division of General Dynamics, 1964. I do hope she was still working when they invented the microchip...

I used to have a Dual 1219 turntable. The platter weighed 7 pounds.
I wonder what the Wow & Flutter spec on that thing is.

The spec on the Dual is 0.06.
Sometimes the Internet is so cool.

Can the driver see where he's going, or is he relying on the horse to react correctly when encountering other road vehicles (horse-drawn or otherwise) and pedestrians?

1931 German automatic make-up dispenser and applier. What could possibly go wrong?
