Are you really really REALLY bored and want 500ish pages listing all the parts/cable/equipment that was available for a BT engineer to order through the British Telecom Stores department in 1996?

Then my friend, I have you covered:

Is anyone able to lay their hands on a firmware image for a Samsung Ubigate IBG1004?

It’s an #isdn to #sip #telephone gateway, and the one I’ve got seems to be corrupt and won’t decompress.

My usual haunts for firmware images are coming up blank.

The filename will be something like `iBG1004_Advanced_1.6.1.9.Z` - but I'm really not too fussy about the version number!

Please boost if you think you have followers that can help!

Ok #vintageElectronics nerds! tell me about these things…

The “MR” designation denotes some kind of diode (it stands for Metal Rectifier, a notation hangover from before silicon/germanium diodes) and they’re obviously arranged as full bridge rectifiers

They’re in a PSU made for the British Post Office in 1972

The brown stripe seems to denote the + end, but what does the other stripe mean?

The (extensive) phone system in my house is reachable from the outside world, but I don't like anyone phoning me overnight.

So I've made all the inbound routes time-of-day aware and they now play this message if you phone them overnight

My #strowger #PhoneExchange installation for #emf2024 is as fully working as it’s going to get… so out come the packing crates!

I’ve got 48hrs to pack it all up before the van arrives…

Packing Progress:
🟩🟩🟩🟨⬜️⬜️⬜️⬜️⬜️⬜️ 29%

I've made another video about getting the #strowger #TelephoneExchange ready for me to take it to #emf2024

In this episode, I try and get the tie lines working...

Oh, and what's that? There's now a website with more information about the #phoneExchange and a blog and everything?

https://emf.lpbk.net/blog/posts/2024-05-05/

The site is a work in progress, and will change a /lot/ in the run up to the event.

RSS feeds are on the todo list, but I've got a phone exchange to fix first!

found an annoying fault on the #strowger #phoneExchange - see that little pin just hanging out there at a jaunty angle nestled amongst the contact springs?

It’s a lifting pin for the contacts at the top of the pile, it’s supposed to be straight, and attached to one of the contacts.

Instead, it’s not lifting anything and is wiggling around connecting things that shouldn’t be connected.

I guess now I get the fiddly job of replacing the stack of contacts without breaking any 70 year old wires!

If I’m going to run a #stowger #telephoneExchange at #emf2024 I need to be able to connect phones to it…
