Lucy's notes on interfacing types (not finished)

6080 Parallel vs. 8080 Parallel: RD/nWR and E

• No difference in performance
• 6080 uses RD/nWR and E control signals
• 8080 uses nRD and nWR control signals

I2C

Pros

• 3 data lines (SDA/SCL/Reset)
• Simplifies D/C by including it in a byte instead of using external pin toggling

Cons

• Only 2 lcds without buses or buffers/switches

SPI w/ 3 wires

SPI w/ 4 wires
