I just received an invoice from ITU
(International Telecommunications Union). Their letterhead states a TELETEX number (in 2024!). I love it. #retronetworking - now I seriously wonder how I might be able to get connected to a public network that can reach it.

@AngelaScholder note that Telex is a rather common #retronetworking technology and you will find many enthusiasts around it, for example in the i-Telex network. However, Teletex is super obscure. I'm one of the few collectors with an actual device, and I know of no efforts to create ant network simulation beyond my humble research and unpublished first steps https://media.ccc.de/v/retronetcall-20230607-laforge-teletex

You gotta love those start trek references in the #linux kernel mailing list infrastructure:

First step is cleaning everything. Somebody spilled some sugary drink over the keyboard, making most keys sticky (in a sense they remain pushed after depressing them briefly)

starting to put together some more information and images about this device at https://osmocom.org/projects/retronetworking/wiki/BildTel_001

Latest #retronetworking acquisition: One of the first commercially available #ISDN video telephones (this unit built in 1992, but I think the model is available 2-3 years longer). Apparently the "Telekom Bildtel 001" was built around a LOEWE MultiTel TV10 BTX terminal, plus an AEG/OLYMPIA codec unit and a TV camera.

I found something that looks like a marketing picture that shows this ancient video phone in action:

ROTFL: There actually is/was medication that they called ISDN (Isosorbid dinitrat): https://cdn.shop-apotheke.com/images/D02/747/140/D02747140-p12.jpg #isdn #retronetworking
