hi all can anyone tell me wat chip is used on a rom card i.e (fun 24c256)
and witch is pin 1 on the card
cheers ime confidant sumone will know
 
Google for ISO7816 it's the smartcard standards and will tell you the card pinout.
 
hi mate
thanks for the reply
but i cant find the manfacturer for this item
can these cards be read with a chip programmer
just a thought as i have a couple of dsd bad cards and thought i could erase them with a progger then read a good 1 and write that to the card
would this work or not
cheers
 
the processor in a ROM10 card is actually a derivative of the ST7 family m8, {the eeprom is anyones guess}--"the r11 will be diffrent again

assumeing you knew the actual chips on the card m8, "what makes you think you could read/erase them with a chip programer"------ if your card programer wont do the job then a chip programer wont either.
 
hi mate
i thought trying to open a program with a program would be harder than erase and rewrite (like a reformat i thought )
would this not be possible
thanks for your reply benny
 
rom cards need to be fully functional and open to erase/rewrite then m8, {you cannot reformat a rom with a chip programer }-------wipe a romcard and it will be useless m8
 
hi mate
thanks for puttin me right again benny
how about fully erase the ic then write a dump from a good 1
its just a long shot as i know a fun card is a atmel 24c256 that i have done this ic b4
i just thought solder a couple of wires to it put em in progger and roberts your mothers brother
cheers
 
dont confuse a funcard with a romcard m8, {you can easily erase a locked fun but you wont do it on a rom the way your thinking}----------its a completely diffrent type of card-------get yourself an unlooper m8

dont need ice scrapers mate have a heated screen
cheers again
 
there's no public software that can fix the atr on a r10/11 m8, the other cards you might open useing diffrent scripts, {you definetly wont open them with a chip programer}
