flyingfisch’s 3d library

I made a simple 3d plotting library today.

Usage instructions and demo are included in archive.

Please post feedback on bugs and what functions should be added.



Happy Thanksgiving!

Also, Apple gets the flu on thanksgiving.

PRIZM Disassembly

1.) Take the back cover off. All the screws are the same so don’t worry.

2.) There are 2 screws connecting the boards to the front, as seen in photo below. Take them out and put them somewhere else (not with the regular screws).

3.) Turn the calc over and hold it by the edges. Now take a damp cotton swab and gently press down on each key until the key is below the front cover. Wipe around the inside of the hole. Now let the key raise back up and wipe the sides of the key. Do this with the rest of the keys.

4.) Put the 2 screws on the back into the boards.

5.) Put the back cover back on. hook it over the USB port and 3-pin port, and then guide the battery springs into their slots.

6.) Put all the screws back in.

I came across this to day while browsing the cemetech archives and I don’t recall seeing a post for it so I thought I would advertise it here.

Help is included in game.


Chesstimer V. 1.1 beta

This is the new version. Includes option to add time after each turn, as well as a pause function.

I made this chess timer in LuaZM.


Simply put it on your prizm.


Run with the LuaZM interpretor. Select the number of minutes you want the game to last with the up/down keys. Press [EXE]. When you are ready to start the game press [F1]. The two bars at the bottom give a large visualization of the time each player has left. When finished, press [exit].


Fischer time, add time after each move, etc.

REPORT BUGS! Seriously, if you can comment the bugs here, I would be greatly obliged.


[LuaZM] Debouncing getkey

I made a simple debouncing getkey code snippet:

if keyDirect(key)>0 then 
while keyDirect(key)>0 do keyDirectPoll() end

The while loop doesn’t let the program continue until the button is pressed.

Angry Birds for the fx9860

Just came across this today…

Louloux made an Angry Birds game for fx9860!

Note: This will not work on Power Graphic 2 calculators.
Update: Louloux made the game compatible. You can use the same link!
