Any recommendations? I'd like one that does both MMJ and RJ45 if possible. Ideal Crimpmaster. Takes interchangeable dies. MMJ is available. Don't get an imitation one. Peace... Sridhar

Crimper

Mark Wickens wrote: Best bet I would have thought was ebay - that's where I picked mine up from - it's second hand and specifically for MMJ. Not sure whether a generic RJ12 crimper may do the job, would depend on how it handled the tab. I've thought about doing a bulk order of MMJ connectors - if there is some interest out there for taking some off my hands I'd consider it. Regards, Mark. I think there are/were crimpers that did manage both. Specifically designed for that. I still have a small stash of MMJ connectors, but I could buy of bunch, if you ordered. Johnny

Terminal (servers), cables (was Re: [HECnet] RHESUS is (finally) up again)

I have access to a source that are starting to use PeeCees with VT emulation instead of real VT525's (not all, but most) so as they transition those little connectors become available for me to take, as they aren't using them anymore and have plenty of spares. Last time I was there I just got handed a "handful". If I get a huge "haul" I'll let the list know. I obviously won't need more than the number of terminal server ports I have ... Fred

RHESUS is (finally) up again

RJ45 MMJ Cables

I have made my own cables in the past, although I've now run out of MMJ connectors. I have a whole reel of cable if anyone needs some, or if you have some MMJ connectors and need cables I can make them up for you. Regards, Mark

RHESUS is (finally) up again

by bqt＠softjar.se

I have someone booting some DECserver 200 which was served by PONDUS:: (It's all in the logs...) Only a couple of days ago. Johnny Steve Davidson wrote: I use NetBSD for both the HECnet bridge link and MOP. Sampsa, when you get a chance put a console cable (and terminal) on the DS200 and power it up. It should tell you the MAC address of the boot host. From there we can figure out which system is actually loading the box. It could be any number of systems on HECnet depending on which one is available at the time of the boot and which ones pass MOP. It could even be mine... :-) -Steve -----Original Message----- From: owner-hecnet at Update.UU.SE [mailto:owner-hecnet at Update.UU.SE] On Behalf Of Mark Wickens Sent: Wednesday, October 28, 2009 04:53 To: hecnet at Update.UU.SE Subject: Re: [HECnet] RHESUS is (finally) up again On Wed, 2009-10-28 at 08:49 +0000, Christine Caulfield wrote: On 28/10/09 08:33, Christine Caulfield wrote: On 28/10/09 02:48, Zane H.

I don't know if the DECserver 200 allows you to hook up system consoles. I know that my 90L+ does not. :-( One problem I see is that you have to boot the DECserver 200 via MOP if I remember correctly before you can use it. Yes, you can use a DS200 for consoles. I used to have one doing just that for quite a few systems. You can mop boot it from link you know ... search for "mopd" That should have bee Linux, not link, sorry. ... it's too early. CHrissie Yes, and netbsd too which is what I was doing till the dang thing died on me. However, phoenix from the flames and all that ;) I'm keen to see how much faster I can get the VT520 talking to the 90M. Regards, Mark.

However, phoenix from the flames and all that ;) I'm keen to see how much faster I can get the VT520 talking to the 90M. The 90M I have must have flash in it of some sort, as it boots if MISER is down, although it takes about 2 days ... ;) I have a line on a 700 with flash so I'm hoping I can "upgrade". You shouldn't have a problem hooking that 520 up to your 90M, because I'm typing this to you on my VT525 connected to the 90M, connected via LAT to MISER and ssh'ed into my main Linux machine. (whew!). This way I don't have to fire any of my workstations up in the morning before I get underway for the day just to check the mail (simplicity, eleganace and all that). I also have a VT220 I'd like to hook up in the living room someday ... :) I figure 50 feet at 9600 would work just fine. Your issue (like mine was) may be cables - either you'll have to use a RJ45 to MMJ cable wired appropriately, or get some of those RJ45->mmj things that plug into the terminal server. I have a wiring guide for DECServers if you need it and can place it on a HECNet accessible drive - just let me know. I have an abomination of a connector/cable hooking the 90M to MISER's console, some DB25-9pin job connected to a null modem adapter connected to a db25-mmj with then some silver satin running to the decserver ... I'd like to clean that up as MISER is in possession of my only null modem adapter!! :) Cheers, Fred ---- Lets call it for what it is - "legacy" is a term that people use in a polite but derogatory manner to imply that the future direction they prefer is not that which they view as the current direction.
