minimalCPM

This is an exploration into the minimal amount of hardware needed to run a "CP/M" machine. The idea is to use a CPU, RAM, ROM, and a single serial port. The serial port is used as both the system console as well as a CP/NET link to a host computer (server).

The idea is to initially use the serial port as a normal character-by-character console to run a ROM monitor. When boot is selected, the serial port is then used to exchange CP/NET packets with the host and run CP/NOS (CP/NET Network Only System).

The intent is for the CpnetSerialServer component to handle the initial console mode and then switch to handling CP/NET packets for the boot.

Subdirectories are organized as follows:

bin:

• A collection of consumables for both the simulation and real hardware.

sim:

• JAVA code for the simulator.

rom:

• ROM Monitor code.

cpnos:

• CP/NET code.

dist

• CP/NET utilities and files needed to run CP/NOS.
