Is this the same CHAOS that can be in IP packets as protocol 0x10?
Yes, and in DNS messages as class 3.
As a reminder, CHAOS protocol is valid over IPv6 as well.
Should not be confused with Chaos VPN, a predecessor to dn42 for linking nstworks of the Chaos Computer Club.
Woaw! You could use a space cadet keyboard with this!!1!
"The transmission medium of Chaosnet is called the ether. Physically it is a coaxial cable, of the semi-rigid 1/2 inch low-loss type used for cable TV, with 75-ohm termination at both ends. At each network node a cable transceiver is attached to the cable. A 10-meter flat cable connects the transceiver to an interface which is attached to a computer’s I/O bus."<p>[...]<p>"The transceiver receives a differential digital signal from the computer interface and impresses it onto the cable as a level of about 8 volts for a 1, or 0 volts (open circuit) for a 0, through a very fast VMOS power FET. When the cable is idle it is held at 0 volts by the terminations. This simple-minded unipolar scheme is adequate for the medium cable lengths and transmission speeds we are using. The transceiver monitors the cable by comparing it against a reference voltage, and returns a differential signal to the interface. In addition, it detects interference (another transceiver transmitting at the same time as this one) and informs the interface."<p>Seems like the above would be all that's necessary for the simplest possible "built around first principles" local LAN, if someone wanted to experiment with an early Ethernet-like system...<p>Anyway, great article!
