Z1RCC has no real ROM. It has a single 512K RAM chip. The RomWBW
|
|
ROMless startup mode is used.
|
|
|
|
The ROMless startup mode treats the entire 512KB as RAM. The entire
|
|
512KB of RAM (less the top 32KB) must be preloaded by the Z1RCC CF
|
|
Loader. There will be no ROM disk available under RomWBW. There will
|
|
be a RAM Disk and it's initial contents will be seeded by the image
|
|
loaded by the CF Loader.
