A minimal UDP/IP stack in FORTH for the N.I.G.E. Machine

The purpose of this package is to support a UDP/IP terminal on the N.I.G.E. Machine via the Nexys4 / Nexys4DDR Ethernet adapter. However it should be adaptable to other systems. See the comments in network.f

Instructions: copy the files to a microSD card, connect the N.I.G.E. Machine to the network with an Ethernet cable, power on, and at the Forth prompt enter

mount
include netnige.f
include network.f
include netcfg1.f 

See the file netcfg1.f for how to proceed from here.

You can also connect two N.I.G.E. Machines together! Do so directly using a crossover Ethernet cable (typically red in colour), or simply by connecting each N.I.G.E. Machine to a router/switch with a standard Ethernet cable. On the second N.I.G.E. Machine use the alternative configuration file:

include netcfg2.f
