Bil Herd - update
by Evan Koblentz 20 Mar '19

20 Mar '19

Bil replied about the Friday classes: "You can put me on the schedule for a class on component aging and the effects on heat, with some emphasis on IC’s but not forgetting things like caps, batteries and some of the other components." I'll update the website tomorrow.

Vintage Server Rack - now FREE to a home (any home)
by Jeff G 20 Mar '19

20 Mar '19

Some months ago I posted a vintage server rack available for trade, I'm now offering this for free to anyone interested. This is a vintage server rack with the look feel and louvers of the 1970s.It originally came with an S100 system that I'm keeping (so ignore the units in the pics), but does have both (white) sides and power strip built in. I believe it also has wheels. Rack rails are round hole. Ground-level drive-up-and-go pickup.

OT: Anyone have full tower ATX case?
by Jeff G 19 Mar '19

19 Mar '19

Just curious if anyone has a spare full-tower ATX case with many (5+) 5.25" drive bays available? Its sort of vintage-computing related as I want to update and fix up my shop mule. Case can be beat up even missing sides for all I care. I'm in the Philly area and would be willing to drive to the surrounding areas, etc to meet up.

Frank had it scheduled for the 31st, the last Sunday of the month, which has been his longstanding schedule practice. Someone at InfoAge assumed that it was the third Sunday of the month (which the last Sunday of the month often is) and put it on the InfoAge calendar that way AND advertised in the local media using that date. Because of that, Frank had to change the presentation date to match the advertising. For future reference (with the exception of this month) the NASA lectures are always scheduled on the last Sunday of every month except December.

Looking for DEC bulkhead cable kit
by Richard Cini 19 Mar '19

19 Mar '19

I also posted this on the VCF Forum “wanted” list, but I thought I’d mention it here as well. I’m looking for the Ethernet bulkhead cable kit for a DEC M7504 DEQNA board and BA23 enclosure. I built my own cable based on specs on-line but I’m only 99% sure I did it right. Even if I could borrow one for comparison that would be helpful. The cables aren’t hard to build but I would like to compare against the real thing if possible. Thanks. Rich Get Outlook for iOS<https://aka.ms/o0ukef>

But don't worry about the Some "generic" rails and someone with a metal brake could quickly remedy that problem. ;) I don't believe you could support that on too many, if any, "drawers" with that weight. A piece of thinner angle iron could be bolted into your rack to hold the drive in it but it wouldn't provide the ability to slide the drive in-and-out.

It worked ok, just be sure you get the conductive side facing away from the foam disc. If I had to do it over, I would likely just use the kit from texelec. It would save a lot of cutting...

Museum report
by Evan Koblentz 18 Mar '19

18 Mar '19

Today we had three or four groups of visitors with mild interest. Martin spent all day continuing his work on the network/cameras project. He ran network wires in the ceiling for all four cameras and other stuff. We'll probably add two more cameras, but not for a while yet, and we ran out of time today. Last time, we put PFsense (software firewall) onto our server. Before it just ran ordinary Ubuntu. Now it runs the firewall 24/7 and supplies DHCP. We had a problem getting the cameras to obtain IP addresses, but we have a plan for fixing that next time. We also rewired basically the whole network. Before, our LTE modem also served public Wifi. Now it is used * exclusively * for getting connecting the firewall to the Internet, and nothing else. Thus our wifi is temporarily down; it'll be back in another week or two when we bring an access point back online (replacing the older Cisco unit with a newer one from another company; I forget which brand Martin said.) All of the network wires from the cables and from elsewhere in the museum now go through a patch panel. I'll get us some matching cords so it looks nice. Right now they are all gray and different lengths ... no good! :) Martin also swapped out our main switch for a different model. The old one only had PoE on half of its ports, and one or two ports seemed dead. The new one has PoE on the whole switch. So it was a productive day, and I learned a few more things about networking.
