If you have problems with some keys this should help you.
1. Simple calculations
Addition
Key in: 1.25
Press ENTER
Key in: math/add
Press ENTER
Key in: 1.75
Press ENTER
The output should look like this:
1.25
math/add
1.75 = 3
Division
Key in: 1
Press ENTER
Key in: math/divide
Press ENTER
Key in: 0.01
Press ENTER
The output should look like this:
1
math/divide
0.01 = 100
Multiplication
Key in: -556
Press ENTER
Key in: math/multiply
Press ENTER
Key in: 5
Press ENTER
The output should look like this:
-556
math/multiply
5 = -2780
Substraction & division
Key in: 1234
Press ENTER
Key in: math/substract
Press ENTER
Key in: 1111
Press ENTER
Key in: math/divide
Press ENTER
Key in: 12
Press ENTER
The output should look like this:
1234
math/substract
1111 = 123
math/divide
12 = 10.25
2. RAM access (read and write)
Key in: 123
Press ENTER
Key in: ram/write/a
Press ENTER
Key in: 9675
Press ENTER
Key in: ram/read/a
Press ENTER
Key in: math/add
Press ENTER
Key in: 1
Press ENTER
The output should look like this:
123
ram/write/a[done]
9675
ram/read/a[done]
math/add
1 = 124
3. Text writing and floppy management
Press SHIFT
Key in: H
Press SHIFT
Key in: ello
Press Ctrl-Left
Key in: world
Press SHIFT
Key in: !
Press SHIFT
Press ENTER
Make sure that you have inserted a floppy!
Key in: floppy/write and this text wont be saved because it was keyed in behind this command
Press ENTER
Key in: floppy/read
Press ENTER
Press UP to eject your floppy
Supported commands:
exit
Interrupts the simulation
math/add or
/p
Add
math/substract or
/m
Substract
math/multiply or
/mlt
Multiply
math/divide or
/div
Divide
ram/write/a
Write value to memory slot A
ram/write/b
Write value to memory slot B
ram/write/c
Write value to memory slot C
ram/read/a
Read value from memory slot A
ram/read/b
Read value from memory slot B
ram/read/c
Read value from memory slot C
system/boost/on
Overclocks the virtual phun-CPU to 200% performance
ATTENTION: Don't forget to type system boost off or exit before leaving the simulation. Otherwise phun would run with double precision on other scenes too! Never forget to type system/boost/off or exit!
system/boost/off
Sets the virtual p-CPU speed to default. Never forget to type this, after using the overclocked p-CPU!
floppy/write
Writes the current screen to floppy (ENTER is not necessary. The computer does automatically recognize this command.)
Make sure that you have inserted a floppy!
floppy/read
Reads the current information from floppy and display it on the screen. (ENTER is not necessary. The computer does automatically recognize this command.)
Make sure that you have inserted a floppy!
