For my application i need to connect a 64K I2C™ Smart Serial™ EEPROM to a PC.
We are using a Money Controls Universal MK4 hopper,
a GPT Argus G3 bill reader and a Mars CF9524 coin acceptor.
The I2C eeprom needs 2 TTL signals(0 / 5Volt), SDA and SCL
SDA also needs to be switchable to input and output.
SCL is only output.
How can i connect this to the Milan interface?

Unfortunately there is no easy 5v connection to the Milan PCI board, nor is
there easy access to the internal I2C bus.
There obviously must be many solutions to your problem, as we don't know the exact nature of your requirement we're not sure which ones would be suitable, so a few are listed below:
1/ The PCI card itself has user accessible E2PROM. While it is inside the
case, it is *not* part of the PC and will retain its contents when removed
from one machine and inserted in another.
2/ We have a USB version of the Milan card in final development. This will
provide storage physically separate from the PC case, although the memory chip will still be a part of the unit.
3/ We could easily design a cctalk memory "module" - this would (probably) contain an AVR processor with on-board E2Prom which could either be soldered on or socketed.
4/ If you need to specifically use a microchip 24C65, we could design the
above unit to use one of these for storage.
