Connecting to HECnet from DEC Legacy 19-20 Oct

by robert.jarratt＠ntlworld.com

I was going to have a go at this today, but thinking about it I am not sure this can work at DEC Legacy or even here at home because it would always be behind NAT. Can we make this work with NAT? What ports would you need? Nevertheless I have it configured with DECnet and I have entered the two SNMP commands below (I used the public community name, not sure if that is right because I know very little about SNMP). The information you wanted was: Your external IP Addres: 86.4.69.74 Your external FQDN: jarratt.dyndns.org Is this a dynamic IP: yes The DECnet area at this location: 5 The source interface on your router: Ethernet0 The email address you want updates sent to: rob at jarratt.me.uk (not sure if this is what you mean, this goes to my regular email address, are we talking about some email capability in the router?) The snmp community from the above directions: public I hope that is the information you need.

Typically you tftp them. If the version you already have on the router supports it SCP and HTTP might also be options. -brian On Sat, Sep 28, 2013 at 11:51:54PM -0400, Gregg Levine wrote: Hello!

Alpha Server 1200 p/s schematics

a little more detail. the x means it uses Class X flame retardant dialectic -- in Germany for sure and probably most the eu, class X dialectic is required if you add filtering. any filter cap that goes between the mains and neutral had be made of class X (or class Y if my memory serves me) material or you can't getter German equiv of the us UL for the device [google this if you want to understand more]. that said, the other thing you will see across mains for safety is a semi-conductor called an MOV (metal oxides varister). it has two pins and looks like a cap often orange red or blue and very glossy material but I would not bet on the color. if the designers of the ps assumed an MOV i'd make sure you replace with that not a filter cap.

Hooking up TOPS-20 to HECnet?

by gregg.drwho8＠gmail.com

Hello! Oh wow. I agree. But that Eclipse. I have fond memories of listening to either a Nova-2 or a Nova-3 or a -4, who evolved into an Eclipse working their way through phototypesetting output and making it available to a variety of output devices. Including two first generation laser based ones and one proof device. It seems like a full century today. But it was about one half to one third of that. That's why Dave that Eclipse is calling me. But enough off-topic. ----- Gregg C Levine gregg.drwho8 at gmail.com "This signature fought the Time Wars, time and again."

No problem. A chemist, eh? Very cool. I have the privilege of working with a chemist now; she and I are collaborating on a fluorometer project.
