ANF10! DISCO DUCK DISCO FEVER ANF10 is a fond memory... Do I remember right that it was based on PDP-8 machines acting as connection points? Did they talk serial lines between each other? =A0 =A0 =A0 =A0Johnny The PDP8 thing is a DN92, it has a sync interface and a bunch of terminal lines and a lineprinter interface. It was supposed to talk to a DS10, sync interface on PDP10 IO bus. ANF10 is talked by the TOPS10 hosts over DTE (to FE PDP11 on KL), DL10 (DEC10 DMA/IObus to Unibus) and NIA-Ethernet (we got a ether_type for it..) There is ANF10 code for PDP11 that run on 40's or 34's. The PDP11 code can talk DDCMP over ASYNC or SYNC interfaces, DQ11, DMR11, DMC11. So you can do Wan things. In Sweden we had DEC10's in Stockholm and Linkoping networked with a 9.6K sync link. The DEC2020 talks DDCP with a DUP11 and a KMC (I think it was KMC, unibus card with microdode that basically did DDCMP.) Anf-10 has link-state routing like OSPF/ISIS but only one area. THere was code to do ANF10 over X.25, but it was to expensive to use on a public x.25 netowork... Hello! If that's the case, then how would these machines communicate over longer distances? For that matter, before Ethernet, and even the current methods of fast connections we have now, would all of you believe that we did use either dial-up on leased lines? Mentioned in Cliff Stoll's book, "Cuckoo's Egg" is how his university was connected to the Internet. It depends on what timeframe, the IMP's had 9.6K and later 56K links between them. There was a pararell and a serial host interface named 1822, and later (some bozo) did X.25 as access host-imp. So they either had a IMP at the University, or a 1822 serial link to an IMP. -Dept of useless knowledge.. -P
