Hi folks, I've got a crazy idea, so please humour me... Does anyone have a length of punched tape they could send me? Ideally tape that is five bit, which is 11/16 inch wide I believe. I'm presuming that there is nowhere to obtain paper tape anymore? Thanks, Mark.

Semi-OT: HECnet gateway to Hercules instance

by b4＠gewt.net

Evening all, I've accomplished a little project I've been working on for the past day or so on-and-off and it seems to be working now. I've got the MUSIC/SP demo going and I've configured MAE (which is also going to be the HECnet<--->UUHECnet relay) to act as a "relay" to this instance. To access it simply: 1). SET HOST MAE 2). Log in as MUSICSP (no password) This will automatically connect you to the Hercules instance. The credentials are hecnet with a password of hecnet1. This SHOULD allow multiple users to connect at once...I've not tested this so let me know. Feel free to request an account. Feel free to play around and send suggestions for improving the "relay"/issue reports my way. Try sending an email to $000. I might bring up a little windows box a bit later to run Sim390 so I can give TCP/IP to this...that would make the relay much more usable. I could also route email to/from HECnet/UUHECnet then. -- Cory Smelosky http://gewt.net/ Personal stuff http://gimme-sympathy.org Experiments

Thanks, the mention of UETP by others also jogged my memory, and I'm playing with SYSTEST right now. Not 100% what I was looking for, but it might be good enough.

Does anything similar exist under VMS? UETP (User Environment Test Package) is the closest analog that I know about. It's included with most VMS distributions. Bob

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

by Paul_Koning＠Dell.com

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
