A few glitches are:
POKE 1867,0 → would delete any user PASSWORD
POKE PEEK(8027)+256*PEEK(8028),32 → would recover contents of MEMO after a RESET ALL
POKE PEEK(8027)+256*PEEK(8028),26 → would hide contents of MEMO, much like a RESET ALL would do, but without losing the programs
The internal function library was programmed in BASIC itself and could be extracted with a BASIC decompiler.
Any function in the library can be executed from a regular BASIC program by using GOTO "LIB0:NNNN" where NNNN is the function number (e.g. 5010 for prime factorization). The command GOTO "LIB0:0400" executes a self-test program.
Characters 252 to 255 were user defined. They could be defined by issuing the command DEF CHR$(n)="HHHHHHHHHH" where n ranges from 252 to 255 and the H's are 10 hexadecimal digits (5 bytes). Every byte defines the pixel pattern for a column. Since a column is 7 pixels high, the least significant bit of every byte is ignored.
The CHR$(26) would activate a different character set for Katakana and Kanji characters. CHR$(27) would deactivate Kanji.
Via a serial cable the calculator could connect to a PC or to another Casio FX-850P, allowing the transfer to MEMO and stored programs.
Cool ! Merci pour le pointeur !et puis y'a la casiothèque ... http://www.casiotheque.com/oisac/doku.php - encore des trucs a explorer


Salut,babaorhum a écrit :Et la genèse de la casiothèque sur MySilicium en 2008 : viewtopic.php?f=46&t=18886
Site super interessant la casiothèque - a poursuivre ?
et pour le rarissime
“FX-850P - Le manuel technique de référence”
un pdf existe t il ??? amis connaisseurs ?


Salut Baba !babaorhum a écrit :Bonsoir Roger !
Merci pour le lien, mais le manuel casio d'origine, on l'a ; c'est le document "OISAC 2 présente :" dont la couverture alléchante est sur :
