Hi all,

I got programmer AllPic and can read and write data on 24Cxx chips.
Does anybody know how to connect wires on Xerox01/90 chip, or have software for this operation.

Thanks

Re: Programmer

You cant read or write all memory area with this programmer. The connexions is same like 24xx

In blue area you can write 1 to 0. Can't revert back to 1 from 0

Pony Prog can do but an older version who know to programm only 1Kb eeprom 24c01.
Programmer is only an interface. The software must do all job.
