A littlebit of interactive experimental computer archeology.
A loooong time ago somewhere in the 1970s calculators entered human 
civilization...

They were seen as supercomputers, sentient A.I. technology, delphic
oracles that could solve all the worlds problems. Of course like any
new technology people would also be against calculators. They would
protest in fear, burn down calculator stores and speak of doom and
gloom for the world if everyone started using one.

The aura of mystery around calculators would be hyped up by books
which showcased all sort of magic tricks and games that could be done on
these wondrous machines.

People would spend their Saturday evening having calculator parties: 
Some booze, some reversed pineapple cake with canned cherries, some
Kraftwerk and Jean Michel Jarre records on the record player and in the 
middle of it all - a calculator.

A whole world of digital wonder and proto cyberspace lay open
in the 9 digit LED screen. The first futile steps in the digital
age had commenced...

Relive these exciting times in this interactive archeology experiment!
Get out your old calculator and astonish yourself and your friends with 
the following calculator games and tricks:

THE DEVILS NUMBER
This game particularly caused an outrage in evangelist circles and got 
the calculator almost banned in the USA. Enter your date of birth in the 
calculator Day/Month/Year If you are born on 22 December 1988 then you 
enter 22121988 now press the divide key and enter the current date.
So if thats 23 december 2020 you type 23122020. Press the = key
now add 1332, press the = key and divide by 2.


CALC'O'WAR
You need 2 players for this. Put the calculator between you and the 
other player. One player holds their finger above the 1 key, the other
player holds their finger above the 9 key. Countdown from 3 to 0 and 
shout GO!. Both players try to press their key (1 or 9) as fast and as 
many times as possible. After 3 seconds both players stop and look at 
the screen - the player with the most digits on the screen has won!


THE LOL TRICK:
A little calculator trick that was popular in Holland.
Flip your calculator 180 degrees, Type in 707 + 707 and see what 
appears! Now this is interesting because of course 707 flipped comes out 
as LOL and the answer is even more mesmerizing. But LOL
didn't mean anything back in the 1970s except in the dutch language 
where lol translates as 'fun'.


MINE FIELD OF CALCULUS
Calculator top entertainment for 2 players. You need a small strip of 
paper to put over the calculator screen.
Give the calculator to the other player. They will enter a secret number 
from 1 till 8 which they will not disclose to you. The calculator is put 
in front of you with the screen concealed with a piece of paper.

The other player now has to traverse on the calculator keys from 0 to 9
without stepping on the mine, which is under the secret key number.

The player starts at 0 and can move to any adjacent number key: up, 
down, diagonal and sideways.

if the player lands on the secret key number the other player shouts 
BOOM! and its game over.

If the player lands on a adjacent number key of the secret number key 
the other will say WARM...or Alert or careful!? whatever you like.

When the player lands on 9 they win and the other player has to give 
them a piece of chocolate.
