I've delt with 3 wire serial connections. Its simpler than I2C because one
wire selects the device on the other end. I2C uses some kind of numeric
code to select a device. Many standard ICs, like 74xxx ones, can be made
to work with 3 wire serial. Some ICs use it directly. Some ICs use I2C
directly, too.
I have a simple setup with a BASIC stamp 2 that uses 4 wires from the
stamp to control up to 8 devices on the serial bus with some help from a
74HC595. It can be easily expanded, but I haven't needed to yet.
