Need a hardware design for an I2C adapter for Win2K for programming PCF8582 device

[Peter]

Some years back I built a little module that allowed me to program a
Philips PCF8582 I2C eeprom./ It no longer works on my newer PC.

Does anyone know of a similar circuit or other method to program this
256 byte eeprom?

Peter,

Elektor published a PC controlled mains outlets box last year using a I2C
chip (PCF8574 or PCF8574A). It used the RS232 DTR - and RTS lines for
bitbanging the data into the chip. I'm sure you can use the same technic to
program your EEPROM but you will need to modify hardware as well as software
to achieve your goal. I used it on a P4 running XP. (I made some
modifications as well. Expanded both hard- and software to do eight bits
instead of six and added the posibility to use a sequencer.)

Not sure about that one, but the Linux source to program a 24C16
i2c eeprom is on:

It uses only 3 parts...
