furrfu = F = G
[TCP/IP hackers] A DEC LSI-11 running a particular suite of homebrewed software written by Dave Mills and assorted
co-conspirators, used in the early 1980s for Internet protocol testbedding and experimentation. These were used as
NSFnet backbone sites in its early 56kb-line days; a few were still active on the Internet as late as mid-1993, doing
odd jobs such as network time service.
