Z80 CPU and Memory Board

This was the first board I built for the computer. I'm not happy with how it looks, but it works. I improved my construction techniques in the later boards.
This board has the z80 CPU, Flash, SRAM, an OR gate for memory address decoding, a 3 to 8 demux for IO address decoding, and a latch that disables the ROM.

The only change I needed to make to this board was adding the latch and IO decoding.
