When was the first computer invented?

I was amazed to find out it was in the 1940s and was the size of a complete room and weighed over 20 ton.

Do you remember your first computer? Was it the 1980s the first home computers were produced?

Yes put together at Manchester University by Alan Turing and others, Alan Turing who broke the Enigma code of the Nazis to help bring an early end to WW11, sadly he committed suicide for being jailed because he was a homosexual.

It was way before that because the first known usage of the word computer was in 1613 although some may argue the abacus. Charles Babbage is generally considered to be the "father of the computer" since he conceptualised the idea of being able programme a machine for multiple purposes.

You could say it was a caveman who invented the wheel to kick start everything.

The earliest acknowledged design for a 'computer' was by Charles Babbage in the 1830's. His Difference Engine (designed in the 1820's) was not a general purpose computer.

The 1830's design was called the Analytical Engine, it was never built but is accepted to be the first design that is Turing complete (a real computer).

Both designs were completely mechanical.

I'm sure I saw Fred Flintstone using one....

A little conundrum.

The first item ever described as a computer? The first mechanical computer? The first electronic computer? The first home computer?

Didn't Sinclair get in there somewhere?

About 2,100 or more years ago the Antikythera Mechanis was created, probably in ancient Greece.

It was roughly the size of a typewriter, and included at least 30 meshing gears. It was probably used to calculate aspects of the calendar.

In answer to the 'my first computer' thing, then disregarding calculators and first 'computer' computer was a Spectrum in the early 80's..

I used to play 'The Hobbit' on it, and also Daley Thompsons Decathlon, amongst other things...The decathlon really used to hurt your fingers, trying to do it faster and faster...

I also programmed a couple of things....One of them was using a weekly magazine, to program a mining game, but I didn't get all the magazines, so only half did the game..

As Brisinger said and Charles Babbage had the help of Ada, Countess Lovelace who was a mathematician , an analyst one of the first programmers and the first person to recognise the full potential of a "computing machine". She was the daughter of Lord and Lady Byron. She met and mixed with most of the scientists of the time and many writers and poets.

Don't forget the Antikythera machine found in a shipwreck off the coast of Greece and thought to be of Greek origin, although no ones totally sure.

After a shot period when I was around people with BBC Apple computers I had some time off them and have never really caught up. I think if I'd not gone to uni and needed one for essays and stuff I'd be struggling more than I do already. To be honest anything more than a basic machine is probably wasted on me, I come on here, send the odd email and check out insurance and bills and do the odd bit of shopping for xmas and birthdays, I don't know what people find to do on them all the time.

I suppose it depends on your definition of 'computer'.

Mine was the one before the Spectrum, was it ZX250 or something? if I remember correctly it had 250Kb's of memory, not the Gb's or Tb's of today's machines.

I was told often that the best computer is the human I used to believe …...but now I think modern computers have so much technology that they are killing the human brain

Beach  Male  Dorset 8-Aug-2019 21:59 Message #4748016
It was the ZX80, Terry. The white / cream coloured one. bought in kit form ... available from the Readers Digest around 1980.

Or ... the ZX81. The black one. A consumer product and the ZX80's successor.

I still have my ZX80.
Aely  Female  Hampshire 9-Aug-2019 22:34 Message #4748165
My father-in-law offered us his ZX81 but we declined. In 1986 we got an Acorn Electron, followed later by a BBC-B. Then came an AST tower (with a CDROM drive!) in 1994. However I first learned computer programming in 1966, writing in Mercury Autocode, a military version based on the old Cambridge Autocode. BBC Basic was an extended version.

My first computer was a Sinclair QL in 1984. Then I bought a ZX80, ZX81 and various kinds of Sinclair spectrum, but I hardly used them. They are in a cupboard.

I bought my first PC at the late date of 1996.

In one of the maths classes that I go to, the leader showed a a simulation of a Turing machine which was two rotatable circles. I said that was a "Two ring machine"!
Beach  Male  Dorset 10-Aug-2019 12:08 Message #4748215
So you bought a QL in 1984 and then 'regressed' back to a 1980's ZX80?
Jeff  Male  East Sussex 15-Sep-2019 20:40 Message #4752777
I've just noticed your post.

I bought the ZX80 and ZX81 as collector's items. I bought the QL for use.

Computerisation and Miniaturization go hand in hand. I wish I still had my old models.
