 This project modifies rev1 Eazy80 pc board so it can accommodate 512K RAM with 16 banks of 32K RAM and a SD interface to run RomWBW. The first step of the modification is to wire in a 74hct32 (quad OR) in the uncommitted 14-pin DIP. The output of the quad OR gates are bank select that drive the 4 high addresses of 512K RAM so the low 32K of Z80 addresses (0x0-0x7FFF) is mapped to one of 15 banks. When high 32K of Z80 is accessed, it always maps to the highest bank, bank 0xF, of 512K RAM. The bank register is controlled by 4 discrete outputs of channel C of PIO, PC0, PC1, PC2, PC6. The second step of 512K RomWBW modifications is adding a SD card to PIO channel B so that PB3 is connected to SD's CS, PB4 is connected to SD's CLK, PB0 is connected to SD's MOSI, and PB7 is connected to SD's MISO.
