A short reminiscence on the motion picture film: 😉 (#2)


"WAR GAMES" from the year 1983:

SHALL WE PLAY A GAME?
Love to. How about Global Thermonuclear War?
WOULDN'T YOU PREFER A GOOD GAME OF CHESS? 
Later. Let's play Global Thermonuclear War.

GREETINGS PROFESSOR FALKEN  ...

HELLO

A STRANGE GAME.
THE ONLY WINNING MOVE IS
NOT TO PLAY.

HOW ABOUT A NICE GAME OF CHESS?

Well, then I'm really glad that I turned this Z80A CMB processor with military specifications into a chess computer.  In this limited memory is also no more space for anything else, there is no 'Dead Code'. Book and fully documented source code SARGON  on 'archiv.org . 🌻🌈 ... Thorsten

... Fun shoots! ? ..Before I draw the coordinate axes of the focusplane in the top pictures (;-),  here is the successor microprocessor NSC800 from National Semiconductor to illustrate the position of the focusplane and its imaging characteristics.

I certainly don't have a problem with that.  (;-) The solution to this challenge has been in the planning stage for quite some time.  I like oak wood and  on occasion I provide the antique board. 😉 Thorsten

Please stop using this ridiculous font, stick to the normal default. Bloody hard to read,especially at the font size you’re using😡😡😡

Hello Everybody,

I think that a variety of font styles is nice. Altho using a font height so that the different font styles are equally readable might be a good idea. Then, people who are interested in the content, who have complexities with reading, can more easily enjoy the text.

Best Regards,

Michael
