The identity number of each station is set up in hardware by links to IC 8. IC 8 is an octal buffer which when enabled feeds the cards station ID to the computer bus.
Each link codes a bit in an eight bit binary number allowing any station ID in the range 0 to 255 to be set up. if a link is left open then the bit is a one, when a
link is made the bit is a zero. Hence all links open corresponds to station ID 255, and all links made to station ID 0. Each station must have a unique identity and
some indentities are associated with specific functions on the network. Station ID zero is reserved for broadcast signals and should not be used. Station ID 255 is
reserved at present for the file server, and 235 for the printer server. Wire links must be soldered to each network station card during installation, a sugested

reserved at present for the file server, and 235 for the printer server. Wire links must be soldered to each network station card during installation, a suggested
scheme for number allocation is to number normal user stations from one upwards and to number special stations and servers from 255 downwards.

Fixed "ERROR" repeating infinite loop, caused by random values in machine_start() being poked into the wrong memory region causing the basic ROM to become
corrupted. Values are now correctly placed in bytes 0x0008 - 0x000B of RAM.
