ANF10 network --> DN200 (RJE, Decnet) --> should be Ddcmp

by R.Voorhorst＠swabhawat.com

Indeed it is Ddcmp, but the meaning is the difference between packet/message oriented and character oriented and the latter should also exist.

Any protocol layered over DDCMP should work. Indeed, and we just proved that with ANF10 which uses the DMCs and DUPs but is not DECnet. Bob

ANF10 network --> DN200 (RJE, Decnet)

by R.Voorhorst＠swabhawat.com

That will probably not realized any time soon. First, all simh sync interfaces speak inherently Decnet (Dmc/Dmr and Kdp/Dup); a simple character based sync line is not yet implemented but needed? Yes!. Second DN200 Rje like DN20/200 Decnet is not like Anf10 but Rsx11S based and it will not(yet) run; debugging is difficult because there almost no source code available to prevent reverse engineering. At the moment, luckily, it already crashes in the Init code and I have the sources for Rsx-11M 3.1 which is the family member of the used Rsx-11S. But there may be more being wrong before we get it running. So far my glazy eyes only see the prompt: DECnet-20 V3.0 Reindert From: Peter Lothberg [mailto:roll at stupi.com] Sent: Thursday, 18 November, 2021 17:16 To: bob <bob at jfcl.com> Cc: Supratim Sanyal <supratim at riseup.net>; R.

ANF10 network --> DN200/DN20 --> instant gratification ...?

by R.Voorhorst＠swabhawat.com

Hi, For the impatient amongst thee I have as interim solution the following, pending the release of the software tree: 1. The load image for simh Pdp11 of Anfu63 being a 5 sync line DN200 with peripherals with node-number 63 (routers top down allocated). 2. The simh config file for configuring a working simh Pdp11/34 with the proper throttling to make it work; the proper setting is important because of Chk11 init phase which is instruction timing based!!! 3. The pdf of the complete listing file of the Anfu63 load image. This configuration maxes out on the number of possible connections to be usable as a star formation router. Beware: the plt plotter device is absent in current simh Pdp11 as I added it in my simh variants for Pdp8A sim (almost finished), Pdp11, Pdp10 and Pdp10-KI/KL; it should not be a problem and can be commented out. The config is for a Windows platform but you Unix/Linux guys will easily hack it into your suitable form. The config file is self-explanatory with respect to interconnecting; I keep a port number allocation schema for all my Decnet/Anf10 nodes. This configuration runs on a Pdp11 simh with a commit date from about 2 years ago, but I do not think it will preclude the current last commit. It you got it running, you can inspect the running node with Ddt11 from a KS10 based system.

Getting reconnected

by b4＠gewt.net

Been awhile since I've posted anything, or been connected but I'd like to work on getting reconnected to HECnet. I would still like to do Cisco connections - just need to pass that through the firewall. Can a more-modern ISR running IOS-XE do DECnet? (specifically a cisco 4321). Worst case I can just re-use the 2851, but that's got a lot of telephony config on it so would like to separate out uses if possible. (Also - you may have previously known me as Cory Smelosky - please update contact details and whatnot) I used to be area 9 - I will continue to use that area.

ANF10 network --> Anf10 KL<>KS + DN200 --> DN200/DN20 parameters

by R.Voorhorst＠swabhawat.com

The DN200/DN20 actually supports 5 Dmc class sync lines with some limitations with number of buffers per line; the system is unmapped i.e. only 28 kW available and only 5 concurrent sync lines of one class will fit comfortably within an otherwise maxed combination of terminal lines and peripherals. I use the Dmc's for that as they will communicate with every class of sync interfaces, so with Dups as well. Mixed varieties of sync lines diminish the max achievable active number of lines. Theoretically one can have more lines per controller and more controllers, but memory constrains what will work. I have not tried Dup's yet for exceeding the pseudo standard of 2 lines.

L.S. Anf10 ethernet and sync lines are 2 separate domains and currently there are no standard interconnections. The (now late) Johnny Ericsson had an Anf10 tunnel but I never tried it. On a KL10 with dte interface a certain routing should be possible, but that cannot yet be done I also restored a DN200 Pdp11 simh workstation (see Anfu63) with terminals and peripherals with remote printing, plotting etc. The network looks like this from the multi kdp/dup node with 2 decnet and 2 anf10 active: .net/t [ANF10 network: connected to ANFW08(57), located at ANFW08(57), 5 nodes] Node ANFW04 (53) 77(8), 55(8), 54(8) Node ANFW05 (54) 77(8), 53(8) Node ANFW06 (55) 77(8), 53(8) Node ANFW08 (57) 77(10) Node ANFU63 (77) 53(6), 54(6), 55(6), 57(6) [DECnet network: local node SWBW08, 8 reachable nodes in area 63] Name Number Line Cost Hops L.Links Delay SWBC01 (63.50) KDP-0-0 7 1 SWBV89 (63.89) KDP-0-0 7 1 SWBW01 (63.51) KDP-0-0 11 2 SWBW04 (63.54) KDP-0-0 12 2 SWBW05 (63.55) KDP-0-1 7 1 SWBW06 (63.56) KDP-0-0 12 2 SWBW08 (63.58) local 0 0 0 5000 SWBX01 (63.41) KDP-0-0 11 2 .net [ANF10 network: connected to ANFW08(57), located at ANFW08(57), 5 nodes] Node ANFW04 (53) Swbw04 Tops10-7.07/34201 01-aug-20 Node ANFW05 (54) Swbw05 Tops10-7.07/34201 01-aug-20 Node ANFW06 (55) Swbw06 Tops10-7.07/34201 16-jul-20 Node ANFW08 (57) SwbW08 Tops10-7.06/34100 27-Jul-20 Node ANFU63 (77) DN200 V25(244) 02-Aug-89 [DECnet network: local node SWBW08, 8 reachable nodes in area 63] SWBC01 SWBV89 SWBW01 SWBW04 SWBW05 SWBW06 SWBW08 SWBX01 Reindert -----Original Message----- From: owner-hecnet at Update.UU.SE [mailto:owner-hecnet at Update.UU.SE] On Behalf Of G.

ANF10 has routing with metrics like DECnet and > RDH even wrote a driver to talk over Ethernet between KL's. If anyone is curious, here below is a link to the ANF-to-Ethernet code by RDH. It contains some nice explanation too :) http://pdp-10.trailing-edge.com/bb-jr93k-bb/01/10,7/mon/d8eint.mac.html G.
