The effects of time travel on consumer electronics is currently unknown .

but remember the prime directive. your little "notes" app would require a warehouse full of vacuum tubes to operate in 1955.

I had one in my Buick station wagon. Well it was a land line. No actually a car line. Whatever.

It was mounted under the dash. I remember when I was at the top of a hill I could access another tower in the next county and get free long distance. Great for having long chats with family.

Remember the song "breaker breaker"

Back in 1967.

When parked in your garage?

That is phones utilizing celluar technology.

The very first cell phone call made was April 1973.

Prior to that, there were radio phones that were extremely localized (and expensive).

back in the 50s, my dad said to learn to type. I'd always have a job!

I'm glad I'm not a hunt n' pecker!

I made my kids take typing as summer courses. They didn't like it, but they're glad now. It provided many jobs for me.

for all the wrong reasons. To be with the girls. But when I went into the Army, it was a highly regarded skill in communications via teletype etc. Then later when computers took over telephone communications (common control switching) the skill was even more valuable

No blood..... no Donnie.
