If you haven’t heard of it, ANF10 (short for “A Networking Feature” – yes, really!) predates DECnet (I’m pretty sure, although I’m sure there will be debate about that) and provides mostly the same functions – remote terminals, file transfer, etc. ANF10 also has remote RJEs with card readers, line printers and terminal concentrators.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal style='margin-left:36.0pt'><span style='font-family:"Courier New"'>.net/anf<o:p></o:p></span></p><p class=MsoNormal style='margin-left:36.0pt'><span style='font-family:"Courier New"'>[ANF10 network: connected to VENTI(20), located at VENTI(20), 2 nodes]<o:p></o:p></span></p><p class=MsoNormal style='margin-left:36.0pt'><span style='font-family:"Courier New"'>Node VENTI (20) SIMH KS10 VENTI 7.04 NET 14-Nov-21<o:p></o:p></span></p><p class=MsoNormal style='margin-left:36.0pt'><span style='font-family:"Courier New"'>Node TWONKY (37) SIMH KS10 TWONKY 7.04NET 15-Nov-21<o:p></o:p></span></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal> It’s possible to run ANF10 and DECnet both, and that’s what we’re doing so TWONKY and VENTI are also available on HECnet. If anybody else has a TOPS10 system and would like to connect it would be nice to add a few more nodes, but there is a problem. TOPS10 supports a maximum of two KDP/DUP lines on the KS10, and you need one for DECnet and the other for ANF10. That means each system can talk to at most one other ANF10 system, which limits the network size to two nodes.
