I'm curious: does it inter-operate with modern
TCP/IP implementations?
This just a guess, but 'sort of'? It _is_ TCP/IPv4, so it's got compatible
headers, but I don't know if other parts have changed enough to make it not
work.
E.g. it probably only supports class A addresses, for instance, which is going
to influence the code for picking the first-hop router.
Also, the only driver is, IIRC, for an ARPANET interface.
