May 5th, 2020 : AKAT-1

The AKAT-1, a Polish made analog computer from 1959.
The world's first differential equations analyzer based on transistors.



Quote:
Jacek Karpiński (9 April 1927 – 21 February 2010) was a Polish pioneer in computer engineering and computer science.
During World War II, he was a soldier in the Batalion Zośka of the Polish Home Army, and was awarded multiple times with a Cross of Valour. Later, he became a developer of one of the first machine learning algorithms, techniques for character and image recognition.

In 1971, he designed one of the first minicomputers, the K-202. Because of the policy on computer development in the People's Republic of Poland, belonging to the Comecon (Soviet directed Council for Mutual Economic Assistance) that time, the K-202 was never mass-produced.
Being a popular war hero who fought the Nazis he might become a threat to the commies
so his creations were not produced and he wouldn’t get personal credit.

He said OK, I’ll be a pig farmer, and in 1981 they let him move to Switzerland.

I'm curious what kind of display, or "output device" that is, but I can't find any details on it.

looks like the xy coordinate system on which one might plot the points of a differential equation

The 2-over-5 (rows of dots) pattern is reminiscent of an abacus, widely considered the first computing "machine" and thus an ancestor of the AKAT-1, and of course all modern computers.



I can't tell if there's anything meaningful in the dots in the strip on the floor. I think it's more likely that someone chose the pattern because it looks kinda cool, and is appropriate for the computer room.

It looks like ASCII punched tape.

Apologies for not posting a link but presently on a superannuated iPad which doesn't lend itself to such niceties.

Perhaps a fellow Dwellar would be kind enough to step into the breach?

I believe it's 2 over 4. Looks like the punched tape used for input on early NC machines in the machine shop.

The ASC II is 3 over 5.

It is 2 over 4. I can't count. And there was even something way, way back in my memory saying that it was some kind of tape, but once I thought it was 2 over 5, I thought of the abacus.

This site has always been a group effort, lord knows I make enough mistakes to keep a bunch of editors busy.
