18. Pinups! Oops! I mean Pinouts :)

I was trying to visualise the connections between the main ICs for my little project. Specifically the address bus pins(A0 to A15) and the data bus (D0 to D7). Looking at 3 .pdf datasheets did not help and what I really wanted was a side by side picture. So I started up Microsoft Paint and started making some of my own images, and here they are:
The Z80, the 128k SRAM and the 8K EEPROM.
