Decided to test and to my big surprise I found out that the blade memory worked in the zx6000. Now I have enough memory. Yeah, a lot of HP gear of the same era uses the RAM This is more like a nice to know post for everybody. Indeed. I more wanted to let folks know I can provide the spares on a sale or trade basis at community pricing (i.e. cheap) as they are still very expensive from most sources. -- Mark Benson http://DECtec.info Twitter: @DECtecInfo HECnet: STAR69::MARK Online Resource & Mailing List for DEC Enthusiasts.

With my connection, I noticed that the circuit would disconnect and reconnect periodically. It corresponded to the timeout in my firewall causing the UDP association to be lost. When I increased the timeout in my firewall for these port 700 UDP "connections", that made my circuit much more stable. Unfortunately, my firewall (a SonicWALL NSA 240) is also stupid in that it *must* randomize the source port for outgoing packets, so I'm not able to connect to HECnet because MultiNet insists that the source port must also be 700 and mine are coming through with random port numbers. --Marc

I see these message about every 20 minutes from random nodes. The error message is almost always: "Unexpected packet type" So where do we go from here? -Steve -----Original Message----- From: owner-hecnet at Update.UU.SE [mailto:owner-hecnet at Update.UU.SE] On Behalf Of Johnny Billquist Sent: Saturday, June 09, 2012 01:15 To: hecnet at Update.UU.SE Subject: Re: [HECnet] netowrk flapping....

LAT works fine in TOPS-20. In TOPS-10 LCP tells me LAT is active, but it does not work (does not even announce itself). How do I enable LAT in TOPS-10? Don't knew. 3) And, spealking of LAT... How do I change the service identification in TOPS-20? What do you mean with service identification? The stuff in "sh exec char?" I mean, how do I change it PERMANENTLY? I guess I have to put it in some sort of auto-executing file. SYSTEM.CMD? Something in 7-1-CONFIG.CMD? Again, any pointer to docs would be very appreciated. I don't want to bug you with the thousands of questions I've got :) Right There is nothing permanent, unless you poke it in to the monitr.exe file....

FWIW, The TFxx drives have DSSI interfaces. The TZ drives are SCSI (e.g. TZ85 or TZ87). The TK drives (TK50, TK70) have DEC proprietary interfaces. A TF8x drive isn't going to do you any good unless you have a MicroVAX with a DSSI controller - Yes, I have two machines with DSSI. a TZ8x drive can at least be connected to any VAX or PDP with SCSI. AFAIK there isn't any difference, other than the interface, between a TF85 and a TZ85, or a TF87 vs TZ87. I don't think there's such a thing as a TK85 or TK87 - DEC dropped the proprietary interface after the TK70s. And I don't think there were any DSSI drives after the TF87. I know I have a TZ85 or TZ87 (maybe even both) somewhere but whether it's any better at reading bad TK50s I won't even speculate. BTW, If anybody has a TF drive that they'd like to swap for a TZ, let me know. I've got a rack of DSSI drives (RF7x and RF3x) that'd love to have a little tape drive for a cousin :-) I too would like to find any TF or RF drives, also would like to find a KFQSA so I can try out my KA655 CPUs.
