Z80 Processor
The processor is what a computer or robot actually computes with. Without one in its processor slot, a machine will not start.
This is an 8-bit Z80 processor. It runs CP/M. It comes with 64K of built-in memory, so it needs very little hardware around it. Devices available through the MLAPI, such as the redstone interface, work as expected. Memory modules, hard drives, network cards and the other native devices go unused, as the Z80 has no use or drivers for them. They can stay on the bus regardless.
Crafting it with blank flash memory writes the CP/M loader. Crafting it with a blank floppy writes the CP/M system.
