Notes
-----
- At startup CPLD ROM is mapped to Z80 CPU address space 0x0000-0x003F, CPU begins execution at 0x0000
- CPLD ROM (CF bootstrap mode) reads CF Boot Loader (512B) from start of CF (MBR) to 0xA000 and runs it
- CF Boot Loader reads Z1RCC Monitor (4KB) from sectors 0xF8-0xFF of CF to 0xB000 and runs from 0xB400
- Z1RCC Monitor reads 480KB (RomWBW) from sectors 0x120-0x4DF of CF into 480KB of physical RAM
