@ety some stuff under #retronetworking too

I posted to my @irishmasms@pixel.infosec.exchange account pictures of my two Lambda LQD-422 dual regulated power supplies. Scored at EFM, but both have issues. Is it worth having them fixed - and who would do such repairs?

The one has the note: CT 1 works, meter bad. CH 2 to rail, Meter bad"

The other has" CH1 & CH2 volts are good. Meter Ch1 is bad, CH2 good?"

I am unfamiliar with power supplies like this; was looking for testing on my bench before I had to dig out the right wall wart and thought these may help.

EDIT: I found this that may help https://www.djerickson.com/lambda/

I posted over on @irishmasms@pixel.infosec.exchange The #mug
I received at #microcenter in #santaclara yesterday.
It is a nice mug, it will be added into my rotation.

The new store, well it is nice to see them back in #siliconValley
Not as nice as I recall their store in #denver and definitely focused on #peripherals targeting #gamer types and #influencers
The selection of #3dprinting supplies was impressive

The crowds was insane - the parking lot was full, lines for support was long, checkout was not that bad. I did not purchase anything though. The couple of items I would have considered was on sale but sold out or was more than I was willing to spend.

I would suggest going in the off hours or waiting until the newness dies down before going.

I just stumbled over this article about the history of video telephony: https://mashable.com/archive/videophone-turns-50 #retronetworking #telecommunications

Wir haben Internet. Sort of.

Für ein Gewerbegebiet, das keine 500m Luftlinie vom Hauptbahnhof weg ist, ist das ein wenig … dünn. Mag uns jemand zeitgemäßes/schnelleres Internet empfehlen? Vielleicht von einem lokalen Akteur? Gerne per PM.

@vuuc im #retronetworking scannen wir viele Bücher und Unterlagen zur historischen telekommunikations-/fernmeldetechnik, Schwerpunkt späte 60er bis 2000, teils aber auch älter. Mich würde die Liste der Duplikate interessieren.

A day that starts with a #clabretro upload and promises of D&D later in the day? Not a bad day at all.

Clab continues to scratch my #Retro #Sun itch with today's upload: https://www.youtube.com/watch?v=PKPVI-qFjLU

on my way to the optional friday meeting of early arrivers to RetroNetConf, our small German-language meeting of various #retronetworking enthusiasts https://osmocom.org/projects/retronetworking/wiki/RetroNetConf_2025 #telecommunications #isdn

Für episodenechte Vernetzung suchen wir …

• RS232-Karte für Apple II bzw. ][
• schnelle RS232-Karten für Amiga 2000/3000
• schnelle RS232-Karten für Mac Nubus (030/040/PPC)
• RS232-Karte für Acorn RiscPC oder A3000

Im FreiȻIX können wir jetzt endlich ARCNET routen bzw. verarbeiten, dank zweier neuer THOMAS CONRAD Karten. 2,5 MBit/s per Coax über RG-62-Kabel. Token Passing!

Heutzutage sind die meisten CIX’e ja soooo festgefahren auf Ethernet … wir sind da offener!

@bagder @m4rc3l Pay for my secrecy by supporting curl on Apple A/UX and Atari MiNT … hey, why are you pointing that pointy thingy at me?

This time we're netbooting OS/2 Warp.

@vga256 The Cisco 2500 is a mighty box for its time, and for sure it can route faster than a LC475 – if you’re running Mac OS on the Mac and not some BSD.

But in terms of raw CPU performance, the LC’s 68040/25 runs circles around an 68030/25, it is 2-3 times faster due to the large 8 KB L1 cache and optimizations.

does anyone know a museum or collection that contains a working/operational Ericsson AXE10 digital telephone exchange? #telecom #ericsson #history #retronetworking

I got an #analog #rotary #dialphone #Vorzimmerapparat 38" by "VEB #Fernmeldetechnik Nordhausen", used in a two-#extension-boss-secretary-#pbx, and #modded it to work on public #phone lines (#POTS), while giving the existing user interface elements meaningful uses:

* Faintly glowing LED while on hook and flashing while #ringing
* Buttons: Earth, flash, mute microphone

#Video of the ringing #telephone (with sound) is here: https://faircloud.eu/nextcloud/index.php/s/jDgS9XgBXAY7gjq

@steely_glint @voltur In terms of people I know: @hanshuebner was certainly a "creative" user of X.25 back in the day and still plays with it today, primarily in the context of VAX machines, AFAICT. #retronetworking

upstream #linux #kernel developers talking about removing the in-kernel echo cancellation code that has no in-tree users anymore (however, out-of-tree DAHDI can optionally make use of it). See https://lkml.org/lkml/2025/2/23/416 and the responses for details. I don't think it's critical at all. #retronetworking
