DMC11 in next simh version... looks nice, and question about TOPS-10

Following up a second time on my own note... On Jan 4, 2013, at 8:31 PM, wrote: Following up on my own note... ... More precisely, the answer depends on whether you want to be strictly compliant with the DDCMP spec, or "compliant enough". DDCMP guarantees the following: 1. Nothing sent prior to the most recent DDCMP restart will be received after that restart. 2. If packet n is received, packets 0..n-1 (counting from the most recent restart) have also been received 3. Packet boundaries are preserved (packet boundaries are significant) 4. If a transmit n completes, that means that packet was delivered to a buffer on the receiving node. It turns out that only properties 1, 2, and 3 are required for DECnet Phase III and beyond; that's because the routing layer is a datagram service so the layers above can't draw any conclusions from transmits completing. It's possible that DECnet Phase II requires property 4; I'm not sure and I don't really know how to answer that question since I haven't seen copies of the Phase II specs online. I have since found the Phase II specs online. The answer is yes, Phase II requires property 4. In Phase II, there are no NSP retransmits. The assumption is that either the datalink layer transmit succeeds (which means the packet was received by the other node) or the datalink layer is reinitialized (which as a side effect causes all NSP connections that use that path to be aborted). There is some extra complexity in this area if "intercept nodes" are present -- a way for Phase II to route across two hops, to support star shaped networks. I'm not sure how widely that is implemented. The only implementation I know even slightly is DECnet/E -- as far as I remember, it contains no support for talking to intercept nodes. It certainly does not contain any support for being an intercept node itself. paul

Tachometer optosensor for RA8x drives?

by bob＠jfcl.com

Does anybody have any spares (or know of a source for) the opto sensor that s used with the tachometer disk on RA80/1/2 HDAs? I have a VAX 8350 with a dead RA81 that d work if I had a replacement (I ve confirmed that by swapping sensors with another drive). Thanks, Bob Armstrong

User Mode Router Developments

by robert.jarratt＠ntlworld.com

I have been working at implementing bits of NSP and NICE on my user mode router. I am not quite ready to release code yet, but it would be helpful if people could try it out. At the moment it only supports the following commands: SHOW KNOWN CIRCUITS SHOW ADJACENT NODES I chose those because they are the ones needed by Brian Hechinger s mapping program. The node name is A5RTR. I am thinking of adding some support for counters so I can monitor activity and then just tidying it up and releasing the code. Note that I don t implement large swathes of NSP, just what I have found necessary to support the above commands. Regards Rob
