Are there any programmers with experience with the Atari 8-bits that may have experience with reading and writing eeproms vie their cart slot?

I'm making a hardware device that goes in the left hand slot, and would like to add a microchip eeprom that is SPI based, and would like to access it ...

The only issue with Renesas is availability of the line. They seem MUCH more interested in the H8 (Hitachi) series than the Mitsubishi series...

Would it be too much to just steal the circuit from an Atari or C64? Schematics are available, and you KNOW the circuit works.

Just an idea....
